The number of people using air purifiers within the home has risen considerably over the past decade or so. Mainly this is because people want to improve the air quality within the home. But why you may ask, has it suddenly become so bad that there is a need for these machines to exist in the first place?

Unfortunately, the answer to that question is due to a number of factors, but ultimately, it’s because of the general rise in global air pollution. And while we may not be able to control the air quality outside the home, when it comes to improving it inside the home, there are options – i.e. an air cleaner in the form of an air purifier.

Recent years have seen extensive research carried out in this area, specifically looking at the effectiveness of air filters and their efficiency in successfully reducing particulate matter and allergens indoors.

This of course is hugely positive and can lead to significant health benefits to those that suffer from asthma or other cardiovascular issues.

However, there are also a lot of questions emerging as to whether or not these appliances can make you sick. In this article, we will look to dispel the myths and reveal the facts so you can decide the best course of action for you.

Are Air Purifiers Safe?


Air purifiers work by removing harmful allergens and other airborne particles from within the home. The way in which they’re designed allows them to draw in unfiltered air and pass it through a filter so that it comes out as ‘clean air’. They can be a great help to anyone who suffers with asthma, allergies, or any other underlying health conditions.

Most decent air purifiers available today are equipped with high-efficiency particulate air (HEPA) filters, meaning they have met the stringent standards of how effective they are. To qualify as a HEPA filter, air purifiers sold in the USA must be able to remove a minimum of 99.97% of any particle with a diameter equal to 0.3 micrometer. This percentage must also increase when the particle size falls above or below this size.

Quite simply, air filters and air purifiers are preventing us from breathing in dirty air, and if they weren’t deemed to be safe then they wouldn’t be HEPA approved.

Do They Dry Out the Air?

In a nutshell, no. Contrary to what a lot of people are led to believe, air purifiers don’t change the humidity level in the air. They are not designed to do this and are not equipped to do this. While air is filtered through the system, there’s nowhere for an air purifier to capture moisture from the air.

If you use an air conditioner, this could be one reason as to why you have dry air. To counteract the effects of this, some people choose to use a humidifier within the home. But we’ll leave that for another day and you can check out our full guide on the differences between air purifiers and humidifiers here.

Can They Make You Sick?

An air purifier alone should not make you sick. Yet there are still a great deal of people questioning this. In this section, we’ll take a look at some of the main areas of concern and whether there is any truth behind the claims.

Sore throat

If you’ve got a HEPA air purifier, this one couldn’t be further from the truth. Because air purifiers work to remove bacteria from the air, they actually help in reducing the occurrence of sore throats and sicknesses. They’re also very effective at eliminating allergens too and can work wonders when placed in the bedroom to help ensure you get a peaceful night’s sleep.

If, however, you have an ionizing air purifier you may experience a slight throat irritation. This is because air ionizers work slightly different to HEPA air purifiers. Instead of taking in air to filter it, they emit charged particles into the air to clean it instead. An unfortunate byproduct of this process is a tiny amount of ozone. And while it is only a very small amount, it is enough to cause people with chronic respiratory system issues, minor throat irritation.


One of the most commonly asked questions relating to health we receive is: “Do air purifiers cause headaches?”. Referring back to the above section on sore throats, provided you have a HEPA air purifier, this should not be an issue as they work to remove any harmful allergens, mold spores, or odors that may cause a headache. It’s also important you consider the right location for your air purifier, if you do that then you should see the quality of the air improve dramatically within your home.

Even those ionizing type air purifiers shouldn’t be a problem as the trace amount of ozone that’s emitted from them is not enough to cause a headache.


This is definitely an unsubstantiated claim regardless of the type of air purifier you have. Other than those instances relating to underlying medical conditions, nosebleeds can also be caused when the air is dry. However, air purifiers do not dry out the air. Therefore, they cannot be a trigger for nosebleeds.


Similar to that of the nosebleed scenario, if you’re breathing in dry and dusty air, it is likely to make you cough. But with an air purifier in the room working to remove any allergens, pet dander, and other irritants from the air, the chances of you coughing should be reduced significantly.

How to Ensure You Air Purifier Doesn’t Make You Sick

While the air purifier alone is not enough to make you sick, combined with a number of other factors, it may. The following are just a few helpful hints as to what you can do to prevent this from happening:

  • Avoid Ozone gas-producing air purifiers: Overexposure to ozone gas is extremely dangerous. Not only can it cause coughing, wheezing, and a tightening of the chest, in some extreme circumstances it can be fatal. Even a small amount can cause inflammation in the throat and lungs. Therefore, it’s best to avoid air purifiers that emit ozone gas, regardless of how effective it claims to be. The best way to do this is to opt for a HEPA air purifier. With one of these, you avoid ozone gas altogether.


  • Clean or change the filter regularly: Having a dirty filter in your air purifier is just as bad as not having one at all. To ensure your appliance remains effective at removing pollutants it’s vital that you clean or change your filter regularly (in accordance with the manufacturer’s instructions).


  • Use natural air purifiers as well within the home (i.e. plants). The air within the home is full of dust mites, allergens, pet dander, and other harmful lung irritants. And while air purifiers are very effective at filtering the air surrounding them, they simply can’t get everywhere at once. So, in order to achieve the very best air quality you can at home, try to use natural air purifiers in addition to an electrical one.

Some plants are very good at absorbing harmful toxins from the air, particularly in areas of reduced air flow. Spider plants are good for this and are easy to maintain. Bamboo palms are even better but take a little more looking after. Both are non-toxic so are safe for those with kids and/or pets.

Beeswax candles also act as natural air purifiers. These burn very slowly and produce very little smell or smoke. Yet they are highly effective at neutralizing toxic compounds and removing harmful allergens from the air.      


If you experience any of the above symptoms while in your home, then the chances of these being side effects caused solely by an air purifier is slim, and almost non-existent if it’s a HEPA air purifier but we always recommend speaking to a medical professional if you’re worried.

Your indoor air quality will improve significantly through the help of a high-quality air purifier. Not only will it help to eliminate any dust, pet dander, allergens, or other irritants in the air, it will also help rid any nasty odors too.

Best Air Purifier Brands

Over the past several years, the air purification industry has evolved. To that end, consumer demand for clean air in the home has risen with it.

In response, numerous air purifier brands have also seen a rise in popularity. In this time, many of those brands have released new models designed to fit every possible consumer when it comes to air quality.

However, even with lots of options, it may be hard to find the best air purifier with just a simple search on Amazon. As it turns out, it is a lot easier to start your air purifier search by finding a trustworthy air purifier brand and exploring their product range from there. This can then help you narrow your shortlist and find an air filter that effectively meets your needs.

With this in mind, we’ve taken the time to compare several top air purifier brands side-by-side. Herein, you’ll find useful information about each brand and their air cleaning technology. Also, we’ve taken the time to read through hundreds of consumer reviews of each brand. As such, you can trust us to provide you with trustworthy information that will make it easier than ever to find a great home air purifier.

A Comparison of the Top 5 Air Purifier Brands

If improving your home’s air quality is your goal, then these are the brands you need to look to first. All 5 of these air purifier top brands will provide you with a reliable product. That being said, each has differing capabilities when it comes to purifying the air. As such, you should take some time to compare these brands and find which brand-specific features suit your home’s needs best.

You may have already noticed that Alen, Winix, Austin Air, and Molekule are not included in this list. While we like these air purifier brands as well, they simply didn’t measure up to these top five picks in several key areas. If you end up passing on these following five purifier brands, be sure to give those other four air cleaner brands a closer look.


First up is Honeywell, who is easily one of the most popular air purifier brands on the market today. That’s likely because their products cover a wide price range, which is ideal for shoppers on a budget. Even so, Honeywell’s most affordable models still provide a solid fan speed relative to their price. Honeywell purifiers can have a high noise level, though, which can be a bother in small rooms.

Regardless of which Honeywell model you pick up, you can count on it to have a reliable CADR. In fact, clean air delivery rate is one of the best specifications throughout the Honeywell brand. This is definitely true of the Honeywell HPA600B, which is one of this brand’s top compact air purifiers. That model utilizes True HEPA technology that allows it to easily trap mold spores and other harmful airborne particles.

Also, Honeywell is a US-based company. As a result, you can count on them to honor the 3-5 year warranties carried by most of their products. This is even true of some of their premium models, which feature UV-C lights and ionizers.


Dyson is another well-known air purifier name, though they’re also well known for their vacuum cleaners. In fact, you could argue that their introduction of their “Air Multiplier” back in kicked off a new interest in air flow technology. That’s because that premier model lacked any visible fan blades. This made it far safer and efficient than traditional blade-based fans.

Since that time, Dyson has implemented all kinds of new air quality monitoring features to the purifiers. For example, some of their high-end models include special HEPA filter sensors that can detect VOCs (volatile organic compounds) in the air. They’ve also introduced “ultraviolent cleansing” technology that have new meaning to in-home air purifying.

Dyson is a UK-based company, though its products are available in many countries (including the US). In almost all cases, they cost more than their closest competition. However, you get what you pay for with a Dyson air purifier. That is to say, with a Dyson purifier, you always get an air cleaner that is built to last. At the same time, the Dyson name always signals a refined attention to detail that translates into enhanced performance.


Blueair is not as well-known as a brand in the US. However, over in China and India, this name is associated with their top-tier performance. In particular, these units are known for their filtration system, which can handle urban levels of pollution with ease. They also always come with high CADR and ACH ratings, which are clear indications of their practical capabilities.

Many Blueair purifier users have noted how quiet they are when in use. As such, their noise levels are rarely a problem when used in a small room. That being said, Blueair purifiers appear to be capable of handling large room air purification as well. The Blueair Pro L, for example, features an auto-sensor that can detect across a wide room easily. Its sleek design doesn’t cause it to take up too much space, though.

Also, it’s worth noting that Blueair are the inventor of the HEPASilent technology. This innovative system is rated to remove 99.97% of particles from in-home air. At the same time, it barely creates any noise while active. This technology has allowed Blueair to gain some professional acclaim. In particular, the Association of Home Appliance Manufacturers has verified their performance claims on multiple occasions.

Rabbit Air

No list of the top air purifier brands would be complete without discussing Rabbit Air. Despite gains from other companies, Rabbit Air has remained this market’s top dog since 2004. This is primarily because Rabbit Air has remained on the front lines of indoor air quality innovation. Despite this, they’ve managed to keep their prices fairly stable, with many popular models costing only around $500.

One such popular air purifier is the MinusA2. When it was released, this model wowed the market by providing medical-grade filtration at a fraction of the price. In fact, it immediately replaced IQair’s purifiers when it came to top-tier allergen removal. The MinusA2 is also able to conservatively use power, making it an ideal choice for daily use in homes with large room sizes.

Rabbit Air is also a US-based company, with its products made and shipped from California. As such, their 5-year warranty is worth paying a little bit extra for. That warranty also comes with 24/7 customer support at no extra charge. That can be a major asset, especially if you need help performing a filter replacement.


Finally, we come to Coway, another reliable name in the air purifier business. This Korean-based brand has long had a major presence in the US market. This is especially true of the large-particle filtration market, where their models have remained popular. The Coway AP-1512HH, for example, uses a pre-filter system that removes odors effectively. It also includes a sensor system that responds actively to airborne particles in any size room.The Coway Airmega is also a great option if you’re looking for a model with a true HEPA filter.

Coway air purifiers are also champions when it comes to filtering out pet dander. These allergens often clog up HEPA-type filters, requiring more frequent replacement. Coway’s activated carbon filters can hold tight to these particles, as well as those produced by dust mites. Many of Coway’s top models are also Energy Star rated, as well. As a result, they’re a great option if you are trying to reduce your home’s energy consumption.

Considering their overall performance, you might expect to pay up to $500 for a Coway purifier. But in fact, some of their mid-range units run for only $200 right now. That’s a considerable bargain, especially for such a reliable unit. Those mid-range units can cover a lot of square feet, too, so you won’t need to pay extra for an extra-large model.


As you can see, these 5 air purifier brands really are the best in the business. Each excels when it comes to different features and specifications. But taken together, they can all be trusted with keeping your home’s air as crisp and as clean as can be.

However, you might still be wondering where brands such as GermGuardian, Whirlpool, and Levoit fall into this list. These are also popular home air filter brands, though if we were to review every air purifier brand out there we were afraid this guide would have gone on forever. As such, they’ve been left out of this top 5 collection. Even so, you may still want to check out their products if you need a specific kind of HEPA filtration.

Where is the Best Place to Put an Air Purifier?

When people talk about pollution and “bad air” they’re usually referring to the dust, dirt, and other harmful toxins found in the air outside. But there are just as many dangerous pollutants living in the air we breathe indoors too. And this is the main reason for the development of the air purifier. These air purification appliances work wonders at helping to maintain good air quality within your home. They remove harmful pollutants, allergens, and bad odors from the air and can help improve the quality of your life. And there is a great deal of choice out there too.

But the problem is not in finding a decent air purifier, (as there are a few), it is in choosing the best place to put an air purifier in your home.

Does it Matter Where you Place an Air Purifier?

Yes, yes, yes! While many buyers recognize the need for an air purifier, they don’t always understand the importance of positioning. Where you place the air purifier within your home, is almost as important as the appliance itself.

There’s no point in spending your hard-earned money on a really good air purifier only to place it in a location where it’s going to have very little or no effect.

What Room is Best for an Air Purifier?

To be honest, there is no hard and fast answer to this question as the best room to place an air purifier will vary depending on various things within the home, such as kids, pets, and room size.

One of the preferred locations for many people is the bedroom because this is where as much as a third of your day is spent. Breathing fresh air at night could help to promote a better night’s sleep. And, there are several air purifiers out there designed specifically for the bedroom, which not only look great but function very well also.

Another popular choice in which to place your air purifier is in an infant/child’s room. Having clean air as they grow and develop is vital for young people as they’ve not yet developed a strong immune system to fight all the harmful toxins, pollutants, and allergens that adults can. Placing an air purifier in your childs room to help with air circulation while they play and/or sleep can help reduce the risk of developing respiratory problems related to unclean air.

If you spend a lot of time in the living room, you may want to consider placing there. While both the kitchen and bathroom are also good locations as they tend to be the worst for producing harmful pollutants and nasty odors. And, the closer you place your air purifier to the source of bacteria or odor, the more effective it will be.

Key Factors to Consider When Choosing Where to Place an Air Purifier

Finding the best place for your air purifier needn’t be difficult. But it does require you to think about a few key considerations, which could sway your decision one way or the other:

  • Size of the room: This is probably the most important factor to consider when making your purchase. Placing an air purifier in a room that’s too big for it to handle is a common mistake. But, it’s also one of the worst as it won’t be able to filter all the air, leaving it contaminated with harmful irritants, and deeming it pretty useless. To avoid this happening always make sure you check to see what the recommended room size is for the air purifier you’re buying. This will quite often be shown in square feet, so it’s a good idea to get your room measurements before shopping. If you’re looking to get an air purifier that’s portable so you can filter the whole house throughout the day, just be sure that it’s capable of purifying the largest room.
  • Avoid corners: For an air purifier to work at its best, it needs to be out in the open where it can pull air from all directions. So, part of your air purifier placement strategy needs to involve keeping it out of the corner. The best location for an air purifier to sit is somewhere it can get good air intake. If your home isn’t particularly big and you find you don’t have a lot of free space, there are some air purifiers that can be mounted directly on the wall. While they may not be able to take in air from every angle, it will be better than placing it in a corner.
  • Position near odor: If you have pets, kids, or even smelly partners, then using air purifiers within the home is a must. Pet dander consists of tiny flakes of dead skin that is shed naturally from dogs, cats, and pretty much any other animal with fur or feathers. For some people, pet dander can cause a great deal of irritation and is the main cause of pet allergies. But thanks to these portable little air filtration systems, a lot of this dander can be removed from the air. There are many good air purifiers on the market aimed specifically at pet owners. Not only do these work well at removing pet dander, they also help to eliminate pet hair and smells too.
  • Doorways are good: If you can get away with it, placing your air purifier near the doorway is very effective in helping to maintain good quality air and proper air circulation throughout separate rooms in your home. A good portion of the harmful pollutants found within the home have been transferred there from outside. By positioning your air purifier in the doorway, you are preventing all those unwanted airborne particles from entering the room.

Should I put my Air Purifier on the Floor?

Wherever possible, you should always try and raise your air purifier to keep it off the ground. However, models do vary across the board and it’s always best to check with the manufacturer’s recommendation first.

There are two main benefits to be seen from raising the height at which your appliance sits. Firstly, by elevating the air purifier, you’re increasing the machine’s floor-to-ceiling efficiency by capturing pollutants near the ceiling faster. This means there’s less chance of them reaching the air you’re breathing. Secondly, it makes the air purifier less of a trip hazard.


Making the decision to buy an air purifier is one that you’re unlikely to forget. Not only will it give you better air quality to breathe, but it will also help keep any unwanted odors at bay too. And now you know where to best position your air purifier, you should start to see some real improvements.

Air purifiers need not be an expensive purchase these days and are much better for you than having open windows in the home letting in all the polluted air from outside, particularly if you live in a city where airborne particles are an issue. So, if you are looking for an effective solution to help reduce the air pollution within your home and make your air cleaner, investing in a decent air conditioning system is a no brainer. It will help bad odors at bay and improve your overall indoor air quality.

What Are the Types of Air Purifiers?

When most people think of air pollution, they automatically assume it’s in connection with outdoor air.

However, indoor air that’s found within most of our homes is not as clean as you’d think and can in some cases, be just as harmful to your health.

Indoor air contains a variety of contaminants including pollen, pet hair, mold spores, dust, and viruses. Long-term exposure to any of these things can play a significant role in the damaging of your health, particularly if you already suffer from any pre-existing respiratory problems.

Using a good quality air filtration system within the home can help protect your health significantly by ensuring you always have a fresh and clean supply of air to breathe. These devices come in all kinds of shapes and sizes. In addition to that, they also differ in the way in which they clean the air. In this review, we’ll go through some of the different types of air purifiers available to buy. We’ll also give you some idea as to how each of the work, why they’re so effective, so you can decide which is the best air purifier for you.

HEPA Filter Air Purifiers

HEPA stands for High Efficiency Particulate Air and air purifiers fitted with these kinds of filters are some of the most popular and commonly used on the market today. One of the reasons why they’re so widely used is that they’re so effective. True HEPA filters are capable of capturing up to 99.97% of air particles and contaminants that are 0.3 microns and larger. They create no harmful byproducts or ozone and are highly reliable.

To give you a brief idea of how they work, HEPA filter air purifiers draw air into the machine via a fan. The air is then passed through a kind of pre-filter in which to trap any airborne contaminants and larger particles. Then, the HEPA filter sets to work removing all that remains. For more detailed information on how HEPA filters work click here.

While HEPA filters themselves are very effective when it comes to sanitizing the air, they do not have the ability to destroy chemical fumes, tobacco smoke, odors, or gases. So, to combat this issue, most decent HEPA air purifiers will also include some kind of activated charcoal filter alongside it.

Activated Carbon Air Purifiers

If you live in an environment with pets and small people frequently roaming around, you’ll be grateful for one of these. An activated carbon air purifier uses a filter with lots of tiny absorbent pores. As air flows through the filter it reacts with the activated carbon and all those harmful irritants and other air pollutants bond permanently. While this type of filter isn’t capable of removing allergens or micro-organisms from the air, it does capture smoke, odors, mold spore, gases, and volatile organic compounds (VOC).

As a rough guide, these filters need changing around every three to six months, depending on usage, which is about average for any air purification system. The ultimate benefit of having clean filters is that your machine will work more effectively, helping to reduce any allergic or asthmatic reactions.

Ionic Air Purifiers

Ionic air purifiers are often referred to as ionizers or negative ion generators and they work a little different to the likes of a HEPA air purifying system. Instead of trapping pollutants and other airborne particles in a filter, these machines work by producing and releasing negative ions into the air. These electrically charged ions react with positively charged pollutants in the air, causing them to neutralize and fall to the ground.

Negative ion generators are very good at dealing with pollen, dust, viruses, and other airborne particles and they’re also very low maintenance. However, on their own, they don’t remove odors. Another downside is that they also create a small amount of ozone into the air which may cause irritation to the lungs, especially in those suffering from any respiratory conditions such as asthma. They also take a little longer to work than most other types of air purifiers.

Spray Air Purifiers 

While this kind of air purifier isn’t really recommended for long term use, it is an effective temporary solution. Spray air purifiers are sometimes referred to as air sanitizers. These devices contain cleaning agents in which to attack microorganisms and neutralize odors and gases in the air.

They are highly effective at tackling bad odors fast, making them a favorite among those with pets or really active kids and make a great addition to the kitchen, living room, or bedroom. Or, some people use them in the bathroom as a really cool air freshener alternative.

Photocatalytic Oxidation (PCO) Air Purifiers

These purifiers take the processes of cleaning indoor air to a whole new level. You won’t find a filter in these machines. Instead, they use a broad-spectrum UV light, water moisture, and a thin sheet of metal in which to create a chemical reaction that breaks down allergens and other airborne particles. All of this takes place inside a reaction chamber so is perfectly safe.

As the air gets purified it flows back out of the device through the reaction chamber core with the help of an integrated fan. These air purifiers are extremely effective as they literally exterminate every air contaminant it comes across from gases, to viruses, to pet dander, to microscopic particles up to 100 times smaller than what a HEPA filter can capture.

Because there’s no filter, PCO air purifiers are very easy to maintain. All they need is a little wipe down every now and then to get of rid of any surface dust and a replacement reaction chamber every 2-3 years.

Photo Electrochemical Oxidation (PECO) Air Purifiers 

Essentially, PECO air purifiers are an upgraded version of the PCO models. They work in exactly the same way, but instead of using a thin sheet of metal to create a reaction, they have a built-in filter membrane that’s coated with nanoparticles. This causes a much stronger and much faster reaction when exposed to UV light compared to that of the PCO air purifier.

As with PCO air purifiers, these devices destroy every type of contaminant they come in contact with. The only real drawback with PECO air purifiers is that they tend to need their filters replacing around once a year on average.

Ultraviolet (UV) Light Air Purifiers

According the United States Environmental Protection Agency, there are three bands of UV light – UV-A, UV-B, and UV-C. The band used in air purifiers is UV-C light. When this light comes into contact with the air, it disrupts the DNA of bacteria, germs, mold, and viruses, rendering them ineffective.

How well this type of air purifier performs depends on the light’s wattage and the amount of time the air is exposed to the light. Make sure to replace the lamp as per the manufacturer’s recommendation. Just be aware that a UV light air purifier won’t remove any harmful chemicals, allergens, odors, smoke, or airborne particles from the air.

Ozone Air Purifiers

Ozone air purifiers, otherwise known as ozone generators, use oxidant ozone in which to eliminate various contaminants from the air including bad odors, bacteria, dust mites, and more. While ozone does have somewhat of a bad reputation for the harmful effects it has on humans, it’s actually a really good air cleaner. The way the work is by releasing a small amount of ozone into the air in the room. As it spreads it reacts with chemically with the air’s pollutants and breaks them down into water and carbon dioxide mostly.

While these air purifiers are effective, they can be dangerous if not used correctly. Ideally, you don’t want to be in the same room as it while it’s on either. So, the best course of action when using one of these air devices is to turn it on high and leave the room. When it’s finished doing what it needs to do, turn the device off and air out the room before reentering. Just be careful if you suffer with any respiratory conditions such as asthma as long-term exposure to ozone could aggravate the symptoms.

Electronic Air Cleaners

With an electronic air cleaner – the sky’s the limit (or maybe the ceiling in this case)! These devices are well-known for being extremely effective. In fact, they can remove as much 99.98% of allergens, dust, pet dander, viruses, smoke, and fumes within the home.

The way in which these air cleaners work is in quite clever. As air passes through the heating, ventilation, and air conditioning or HVAC system, it first gets filtered through a HEPA-type filter where most of the contaminated particles are removed. Next, the air gets treated with positively charged ions that are generated within the electronic air cleaner. These ions destroy any remaining odors and contaminants, ensuring you get a constant supply of clean air.

Because they’re used in conjunction with your home air conditioning unit and furnace, these air filters must be professionally installed. You also need to ensure the filters are replaced regularly and that the ionizing wires or collector cells are kept clean by giving them a quick hose down once a month or so.

Why Invest in an Air Purifier?

The type of air purifier that’s best for you will depend on various factors and is not a decision that should be taken lightly. The following are a few tips which should help you decide:

  1. Think about what contaminants, in particular, you are looking to remove from the air. It may be that you have a house full of pets and so you’ll probably want an air purifier that’s going to banish pet hair and dander, as well as bad odors. In which case you should look for models that include activated carbon filters
  2. Check out the machine’s capacity and make sure it’s compatible with the surface area of the room you want to use it in. Buying an air purifier that’s not powerful enough for the space it’s going in will have a minimal effect. While buying one that’s too big for the room will work, it’s a waste of energy and money.
  3. Consider the noise level. All air purifiers operate at different noise levels. While some offer a wide range of fan speeds and therefore quieter modes, others are a little limited in that department. So, if you are looking to place the air purifier in the bedroom at all, and don’t want to be kept awake all night by the sound of a roaring machine, be sure to opt for one of the quieter models out there.
  4. Calculate your long-term costs. Owning an air purifier is not just about the initial investment. You need to consider the machine’s running costs too, and that includes power usage, filter replacement, and overall maintenance costs.
  5. Read independent review to reveal both the pros and cons of the various types of air purifiers available, we have many here on Skyonic!

You deserve to have the best air quality within your home. And with the help of a good air purifier, that’s highly achievable. They come in all kinds of shapes and sizes so finding one to fit your free space shouldn’t be an issue.

So, what are you waiting for? Improve your indoor air quality today.

How Do Air Purifiers Work

clean air

Manufacturers offer several types of air purification methods. These include filters, ozone generators, ionization, adsorbents, and UV light.

Many devices rely on more than one method. High-quality machines may cost a few hundred dollars to buy. Over time, you will probably need to spend more money to run and maintain your purifier too. On the other hand, a good air purifier may offer you the best way to improve indoor air quality and keep your household healthy. That’s why it can pay to learn more about how air purifiers work before deciding which one will help you invest in clean air for you and your family.

How Do Air Purifiers Work?

Obviously, some air purifiers work better as air cleaners than others, especially in different situations. Take a moment to learn about various types of air purifiers that you can buy for your home.


The most traditional kinds of air filtration systems use filters. Think of the filters that you use in the air ducts for your home heating and air conditioning system. You may purchase devices that use disposable filters, but some come with washable ones. Denser filter materials can catch smaller particles, and a pleated design may prove more effective than a flat one because it has a larger surface area. To keep your filter effective and efficient, be sure to replace or clean it by the manufacturer’s schedule.

HEPA and ULPA Filters 

HEPA stands for high-efficiency particular air, and HEPA filters must meet Environmental Protection Agency, or EPA, standards. To comply with the HEPA standard, particles of at least .03 microns can’t make it past the barrier more than .03 percent of the time. You might also notice a ULPA, or ultra-low particulate air, standard, which is even stricter. Besides getting used for home air purifiers, some industries rely upon HEPA air purifiers and ULPA filters to keep certain worksites free from contamination and reduce emissions. The EPA suggests cleaning and replacing these filters on schedule to ensure efficiency.

Ionizing Air Purifiers 

Ionizing purifiers work by emitting electricity to give contaminates either a positive or negative charge. The charged particles tend to clump together, making them heavier and likely to fall out of the air. Meanwhile, the device has a positively and negatively charged plate that will attract molecules with the opposite charge. According to the EPA, ion air purifiers are best for small particles, like cigarette smoke, but may not work so well for dust or many other allergens. They may also emit ozone, a controversial byproduct of air purifiers.

Ozone Generators

Somewhat similar to ionizers, ozone generators also produce a charge. Instead of just applying a charge to contaminants, these devices change some oxygen molecules into ozone molecules. These devices are meant to help purify and deodorize. However, the EPA warns that ozone can become a lung irritant and in larger quantities, even a health hazard.


Note that these are adsorbent and not absorbent. Adsorbent refers to a substance that can trap other substances upon its surface. The most common example is activated charcoal. Its porous surface has plenty of tiny crevices to trap molecules. Chemical and electrostatic reactions also help attract particles and keep them bonded to the surface. Manufacturers also use different methods to produce this charcoal to make it better at attracting certain types of contaminants. According to the EPA, adsorbent air purifiers may offer safe and effective purification of gaseous and organic pollution, such as from cooking or chemicals. Like other filtering products, adsorbents have to be replaced on schedule.

Ultraviolet Light 

The EPA suggests UVGI cleaners to scrub the air of many biological contaminants. Ultraviolet light can help destroy bacteria, viruses, allergens, and mold in the air. They also suggest using them with a filter and not as a replacement for a filter. Another kind of UV air purifier is called PGO. A PGO works with catalysts to convert gaseous pollutants into harmless byproducts. They don’t work on particles and should also be used with filters.

Which Kind of Air Purifier Works Best?

Indoor air pollution can pose a health risk. Keeping the home clean and ventilating with outside air may help. At the same time, it’s not always possible to clean microscopic particles. If it’s hot or cold enough to need the air conditioner or furnace, nobody wants to leave a window open. Air purifiers may use filters, adsorbents, UV light, electric charges, or sometimes, a combination of methods to help improve air quality. Look for high-quality and well-reviewed products that have been designed safely and effectively to address your indoor air pollution problem.

Are Air Purifiers Worth It?

Air pollution levels have been on the rise for a long time. Not just in the US, but globally. The increase in traffic, more strenuous manufacturing process, and just a steady incline in people are all factors that have added to this dangerous climb. And while we may not be able to control the environment outside of our home, we do have the ability to change it inside.

According to the United States Environmental Protection Agency (EPA), some indoor air pollutant levels are as much as 5 times higher than outdoor air concentration levels. And when you spend a good portion of your life at home, that’s quite a scary fact to think about, especially for allergy sufferers or those with any pre-existing breathing problems. However, there are ways to improve these statistics, one of which is through the use of an air purifier.

What Are Air Purifiers Designed to Do?

The ultimate goal of an air purifier is to improve the overall air quality within the home. It’s essentially a portable air cleaning system.

Even in the most immaculate of homes, dust, mold spores, and other harmful allergens accumulate, causing the air quality to diminish. This is something that can’t be helped. But what can be helped is the level at which this air is filtered, and that’s what air purifiers do. Air purifiers work by taking regular air in via a fan and filter it through either one or several filters. As the air passes through these filters any dust particles or pollutants are trapped, and clean air is expelled back out.

There are many different air purifiers on the market today. However, one thing almost all of them have in common is the filtration system. In most models you’ll find a pre-filter that tackles the largest particles while a high-efficiency particulate air (HEPA) filter or HEPA-type filter takes care of the smaller ones. Some air purifiers also include activated carbon filters as part of their design, which helps to reduce unpleasant odors massively.

A decent air purifier works extremely well provided you maintain it regularly. This typically involves replacing the filter(s) regularly. However, the frequency in which these need to be replaced will vary across models and is largely dependent on usage. So, just be sure to follow the manufacturer’s advice on maintenance.

Some air purifiers use reusable air filters which are extremely effective at removing large particles such as pollen and dust mites. These filters can be removed easily and washed as often as needed. The downside is in order to keep them working most efficiently, they do need a lot of regular maintenance.

Do Air Purifiers Work?

There’s a lot of proven science behind the effectiveness of air purifiers, most of which comes down to the true HEPA filter. These filters are now an industry standard, and any air purifier not fitted with one should be approached with extreme caution.

The reason why HEPA filters are so effective is they use a dense arrangement of fibers in which to capture airborne particles from the air. Using an air purifier that’s fitted with one of these filters in a location that’s optimal, will improve the quality of the air within the home, ten-fold.

Here are just some of the many benefits to be found from using a good air purifier:

  • Significantly reduces dust levels and allergens: If you’re asthmatic or suffer from any kind of respiratory condition then living in a dusty environment can be extremely dangerous. The same goes for those with dust or pet allergies. However, through the use of a decent air purifier, dust levels will reduce significantly along with the number of triggering allergens. The air in your home will be much cleaner, and you will find yourself being able to breathe more easily. If you do keep any furry friends in your home, there are various air purifiers available that are designed specifically for dealing with pet dander and odors. So not only will it help you breathe better it will help your home smell better too.
  • Absorbs damaging chemicals: Volatile organic compounds, or VOC’s for short, are essentially the gases in which are emitted from a number of both indoor and outdoor sources. However, concentrations of VOC’s are much high indoors than outdoors and can come from a variety of everyday items such as cleaning supplies or paint. Having an air purifier in the home, particularly one that’s fitted with a charcoal-based activation filter, can help to absorb some of these harmful irritants, giving you much better air quality within the home.
  • Improve on general household smells: It’s not just pets that produce terrible smells. Odors in the home can come from a variety of sources including pungent foods, tobacco smoke, and dirty kids. While lighting a candle or opening a window may help to ease the whiff a little, a good air purifier will eliminate it entirely.

Are There Other Ways to Improve Air Quality in a Home?

Having good quality air to breathe is not only our right as a human, but it’s essential in order to maintain a healthy life. While an air purifier is the best solution, there are a number of other ways to improve the air quality within your home:

  • Ventilation is vital: Opening a window may seem counterproductive when trying to get rid of harmful pollutants. However, in the absence of an air purifier, having the windows open prevents dust mites and allergens from building up. If at all possible, try and open windows on both sides of the room. This will create a stronger cross draft, making it more difficult for air irritants to settle.
  • Plants are more than just decoration: You may be surprised to know that plants have some amazing qualities when it comes to improving air quality. In 1989, the National Aeronautics and Space Administration (NASA) teamed up with the Associated Landscape Contractors of America (ALCA) to conduct a study called the Clean Air Study. It was essentially a project to find ways to clean the air in space stations. What researchers discovered is that there are a number of common indoor plants that may help to do this, including bamboo Palm and English Ivy. So, go green and bring a few houseplants into the fold.
  • Vacuum regularly: Vacuuming is another inexpensive way of controlling the number of dust particles that accumulate within the home. As most people already own a vacuum, it’s no extra expense to simply use the one you have. If, however, you are looking for an upgrade, try and go for one that’s HEPA-certified. At least then you will have the added benefit of a decent filter.

So, Are Air Purifiers Worth It & Do You Need One?

Absolutely! Regardless of whether you suffer from any respiratory problems or allergies, a good air purifier will not only improve the quality of the air you breathe, but it will help to improve the quality of your life too.  These appliances are not gimmicks and should not be seen as just another fad. There has been a lot of time and money spent on researching the benefits of using these appliances, particularly in conjunction with the HEPA air filter. And each and every time, research shows a clear reduction in the harmful irritants, pollutants, dust, and other particles in the air while using an air purifier.

While there may be a cost in the initial purchasing of an air purifier, and of course you will need to keep replacing or cleaning the filter regularly which may involve an additional cost. However, the health benefits to be seen from having one in your home will largely outweigh any expenditure. As at the end of the day, there is no price to be put on yours or your loved one’s lives. And if you can improve your indoor air quality significantly with just a small investment, surely, it’s worth it?

In 2018 alone, U.S. air purifier sales increased by a million units and can be found in at least one-quarter of American homes. Since indoor air can contain up to five times as many contaminants as outdoor air, it’s not hard to explain the popularity of these devices. Young children, the elderly, and people with allergies, asthma, and other health conditions can suffer even more from poor air quality.

The Best Air Purifiers for Pets

Making the decision to buy an air purifier to use within the home is the first step to improving the quality of your indoor air, and ultimately your health.

A good air purifier works by removing harmful irritants and pollutants in the air. Bad air is filtered through a complex filtration system and clean air is delivered.

In this article we’ll not only go through some of the things to look for when making your next air purifier purchase, but we’ll also give you the lowdown on some of the best models out at the moment.

Buying Guide: What to Consider When Buying an Air Purifier

With so many different air purifiers on the market today, it can be daunting knowing which model will be the best fit for you, particularly if you’re a pet owner. The following section will give you a better idea of some of the most important things to consider when buying an air purifier:

  • Pet Dander – As much as we all love our pets and couldn’t imagine life without the furry little things, they do come with their own challenges. Not only do pets add an extra odor to the air, but they also add a continuous supply of pet fur and pet dander to the air. These extra particles are diminishing the indoor air quality and can cause great irritation to those suffering from pet allergies, asthma, or any other respiratory condition.No one wants to spend day after day sneezing or even worse, suffering from allergic reactions. So, finding an air purifier that will tackle this problem and help to eliminate some of that excess pet fur and dander is vital. But don’t worry, as there are plenty of decent air purifiers on the market that are specifically for this purpose – some of which we’ll get on to in the next section.
  • Filters – Finding an air purifier that’s equipped with a HEPA filter shouldn’t be too much of a problem as pretty much all of them are, and for good reason too. HEPA air filters clean more than 99.9% of airborne particles.However, there are other kinds of filters to look out for as well. Many good air purifiers use other types of filters in conjunction with a HEPA air filter. For example, carbon filters are sometimes used to neutralize odors, while HEPA filters tackle the actual particles. When you have pets, it’s a good idea to opt for an air purifier that uses a combination of these filters in order to effectively remove any pet dander or pet fur in addition to any bad odors such as those relating to a litter box.
  • Material Type – They type of material the air purifier is made from will largely affect the price as it will affect the efficiency of the product. When it comes to air purifiers, those made with higher quality components are almost always more effective. And, we’re not talking that much of a difference in price. So even if you are on a bit of a budget, don’t automatically reach for the cheapest product as it could end up being completely ineffective, in which case you’ll end up buying the better one anyway.Metal air purifiers are good because they’re tough and long-lasting. The downside is they can be quite heavy. Some plastic air purifiers are also a good choice as they’re affordable, easy to clean, and lightweight. The downside to these is they are much weaker than metal ones, some so much that they shouldn’t be sold. So, just take extra precautions when buying a plastic air purifier.
  • Room Size – The size of the room you intend to put your air purifier is another very important consideration. While it would be great to have an air purifier in every room within the home, it’s not always feasible. In which case, you need to decide which room you’re going to place it.Is it better placed in the living room where you spend a large portion of your time? Or would you rather it went in the kitchen where a lot of the odor in the home emanates?  Once you’ve decided on that, you need to measure the size of the room.


    Having an air purifier that’s too small may help to reduce odors and clean a portion of the air, but it’s not going to work for the whole room. On the flip side, if you buy one that’s too big, you’re simply going to be wasting energy.

Top 8 Best Air Purifier for Pets Reviewed

Medify MA-40

If you’re looking for something that offers a little more than just the basic removal of pet odors, dander, and fur, then the Medify MA-40 may be a good choice for you. Featuring a medical-grade filtration system, the Medify MA-40 is the perfect solution for anyone who has severe allergy symptoms or asthma who may need something a little more effective. According to the manufacturers this air purifier can clean a room up to 1600 square foot in size in just one hour. Halve the room size and the cleaning time is also halved.

In terms of the actual size of the device, the Medify MA-40 is 22” in height and 10 inches in width, making it quite small against some of its competitors. But don’t let that put you off, as it’s still super effective, and much easier to find a home for. On the top of this air purifier you’ll find a tempered glass control panel that’s easy to use and looks pretty cool too.

When it comes to performance, this air purifier is a true force to be reckoned, featuring a comprehensive, 4-stage air cleaning system that’s very effective. The first stage is a washable pre-filter which traps any large pollutants such as pet fur, and large dust particles. Next, the HEPA filter takes over, capturing all the smaller allergens such as mold spores and pollen particles. It then passes the air through an activated carbon air filter in which to remove any toxic odors. And then finally, through an ionizer (although this is optional and can be switched on or off).

The Medify MA-40 features 3 different fan speeds. On speeds 2 and 3 the ionizer can be switched off as and when needed. On the highest setting it measures in at around 65 decibels (dB), which is kind of noisy. However, when it’s on speed 1 or in “sleep mode”, it automatically switched off to help keep the sound to a minimum.

For added piece of mind this air purifier comes with a lifetime warranty.

Hathaspace Smart

The Hathaspace Smart True HEPA Air Purifier is a high-end 5-in-1 air purifier. It works in a similar way to that of the Medify MA-40, with multi-functioning filters, but with an antibacterial filter thrown in.

Measuring in at 13.5” x 7” x 19.5” and weighing just 12 pounds, it’s quite a lightweight air purifier, which is ideal for anyone looking to move it from room to room. In terms of performance, it’s capable of cleaning the air in a room of up to 350 square feet in size and takes about 30 minutes in which to do it. It’s also a very sleek and snazzy looking machine that would look good just about anywhere.

What sets this air purifier apart from the rest is not necessarily its performance (although that is definitely on par with the best). It’s more about the extra smart features it has to offer. For example, there’s a smart sensor on-board that measures the air quality and adjust the fan accordingly to make sure you always get the best air possible. Right on the display itself, it continually displays the air quality within the room on a very easy to read red, yellow, or green scale. This ensure you always know the quality of the air you’re breathing.

It also comes with a handy remote control which allows you to adjust the machine from anywhere in the room. Or, simply activate the “sleep mode” and it will switch off all the display lights and operate at it’s quietest (20dB).

Overall, the Hathaspace Smart True HEPA Air Purifier is a pretty good buy. While it may not have the capacity to clean a large space all at once, it’s very effective in smaller rooms at removing pet smells, pet dander, dust, and other irritants in those areas that it can reach.

Germ Guardian 

One of the most popular air purifiers currently available is that of the Germ Guardian. It’s a 3-in-1 air purifier that’s both effective and affordable and therefore suited to a wide range of homes.

In terms of size, the Germ Guardian is very compact. It measures just 9” x 5.5” x 21.5”, making it one of the smaller air purifiers on this list. It’s also very lightweight, weighing just 7 pounds. So, if you are looking for a portable air purifier to use in multiple rooms, this may be the model for you.

Being a 3-in-1 air purifier means it’s effective in 3 separate areas. It reduces odors and traps allergens that are produced from a range of sources including pets and moldy food. It also uses a UV-C light in which to kill germs. These are especially important features for pet owners as all help to improve the overall cleanliness and freshness of a room. Something that’s easily dampened when pets are around.

There are couple of downsides to this machine. The first is that it’s only effective in a room of up to 167 square feet in size. And, secondly, it produces around 40 dB even on the lowest setting, making it one of the more louder air purifiers around.

On the plus side, you do get a 3-year limited warranty should to experience any problems.

So, while it may not have all the bells and whistles that some of the other air purifiers on this list have, what the Germ Guardian does offer is effective air cleaning in a confined space. It’s lightweight enough to be moved around as often as needed, and it’s very well priced.

Winix HR9000 

Considered to be the next generation of air purifier, the Winix HR9000 takes innovation to a whole new level. This ultimate pet air purifier uses plasma wave technology to break apart and destroy odors, allergens, and other harmful pollutants that happen to be lurking around.

Capable of cleansing the air in a room of up to 300 square feet in size, this air purifier super effective at removing pet hair and pet dander. And thanks to the integrated deodorized carbon filters, it’s also highly effective at absorbing pet odors too.

The Winix HR9000 uses a 5-stage air filtration system that’s one of the best around when it comes to pets. It has not one, but two, pre-filters which capture all the larger particles of pet dander, fur, and dust; an activated carbon filter in which to absorbing all those lingering pet odors; a True HEPA filter that’s capable at capturing 99.97% of allergens and other harmful particles; as well as a Winix PlasmaWave air filter which is a special type of ionizer that further reduces the number of pollutants in the air.

Don’t worry if that seems like a lot of filters as they are pretty robust and last a while. And even when they do need changing, replacement filters don’t usually cost that much.

Measuring in at 16.3” x 9.6” x 23.6” makes it one of the larger air purifiers on this list. However, when you’re a pet owner you’ll know only too well how far pet smells can travel. Having a larger than normal air purifier usually means having larger filters. And having larger filters, means less smell.

In terms of noise, this is one of the quietest air purifiers on the market, with a dB level of just 26, which is little more than that of a whisper.

So, if you’re in need of an air purifier that’s designed for those with a furry friend or two at home, then this may be the one for you.

Levoit H13 Air Purifier

A sleek and classy looking device, the Levoit Air Purifier is fantastic pet air purification system that’s perfect for just about anyone, especially those with pets.

The biggest selling pint of this air purifier is that it’s equipped with 3 unique filters. There’s an ultra-fine pre-filter; a HEPA filter; and a granular activated carbon filter. While the pre-filter can be cleaned regularly to help maintain its life, both the HEPA and carbon filters will need to be changed at regular intervals. But don’t worry as the machine also features a check filter indicator that lets you know when it’s due for a clean or a air filter replacement.

Equipped with Vortexair Technology, the Levoit H13 Air Purifier creates a stronger air flow and is capable of purifying the air in its range up to 5 times per hour. And, the noise level is just 24 dB, making it one of the quieter models out there.

Another bonus this air purifier has to offer is that because it uses no UV/Ion light, there’s no harmful ozone gasses emitted.

However, it is a little on the small side. The Levoit H13 measures in at just 8.7” x 8.7” x 14.2”. And while it’s great in terms of portability, it’s does mean the area it covers is usually less. Covering up to 219 square feet, is not bad coverage for a device of this size, but there are some more efficient models out there for a similar price.

All-in-all, it’s a pretty basic functioning air purifier that’s effective at using to tackle pet dander, hair, odors, and more. Sure, there may be bigger and more efficient models out there, but then you will pay a lot more for them. But if you just want something that’s going to help give you better indoor air to breathe while eliminating some of those (not so nice) pet odors, then the Levoit H13 Air Purifier is a good choice for you.

Rabbit Air BioGS 2.0 Air Purifier

The Rabbit Air BioGS is one of the higher-end air purifiers on this list, not just in looks, but in performance too. It’s the winner of multiple awards including the Red Dot Design Award and the G-Mark Good Design Award.

Measuring in at 22.2” x 16.6” x 9.8”, it’s a pretty big purifier so you will need to make sure you find room for it. But, capable of filtering the air in a room of up to 550 square feet in size, is one of the more efficient models on this list and perfect for filtering any large rooms in the house. This is achieved through the device’s 4-stage filtration system.

The permanent pre-filter effectively traps all the large particles like pet fur and dust mites, before directing the air to the BioGS HEPA filter where any smaller airborne pollutants are broken down. Next, the air is passed through the charcoal filter in which to reduce any nasty odors, before finally making its way to the negative ion generator which helps to fortify the air, making it healthier and more breathable.

There are five different speed setting to choose from on this air cleaner, so it should please just about everyone. Just be aware that while it’s pretty quiet (22 dB) on the lowest speed, on the highest speed it can get as loud as 50 dB. So, you may want to avoid this setting when trying to bed down for the night.

One of the biggest selling points of the Rabbit Air BioGS is that it’s so innovative. To help reduce energy usage, all the lights on the interface will go out when the machine is idle. It’s also fitted with a filter life indicator to let you know when they need replacing. Another very environmentally friendly feature.

As well being an effective air purifier to have if you own pets, the Rabbit Air is also considerate of children too. If the cover of the machine is removed while in use, the device will stop immediately. So, there’s no danger about little hands getting caught where they shouldn’t.

When it comes to selling points, the most prominent feature this model has to offer is the advanced ifD QuietClean technology that it’s equipped with. Don’t let the fact that it has a 2-stage filtration system deter you as it is fitted with some of the most effective filters out there. The first filter is the pre-filter, and this is pretty similar to most other models out there. It’s permanent, and it’s pre-washable.

The second filter is the Intense Field Dielectric (ifD) filter which effectively captures up to 99.9% of airborne particles including bacteria, pollen, viruses, and pet dander. It also includes a part of it an activated carbon filter to help contain bad odors. These filters are one of the only types that’s comparable to that of HEPA filters in terms of protection.  Another benefit to be seen in an ifD air purifier such as this, is that it’s much quieter than a HEPA filtration system, even at top speed.

Capable of filtering a room that’s up to 250 square feet in size, the Honeywell HFD320 AirGenius 5 has a total of 5 different air cleaning levels to choose from. There’s a general setting, a sleep setting, a max setting, a germ setting, and an allergen setting. So, you can change the speed, depending on what it’s to be used for.

Air Purifiers FAQs: Do Air Purifiers Help with Allergies?

Allergy symptoms occurring in the nasal passages, eyes and throat are caused by airborne contaminants. Common allergy symptoms include sinus drainage, post-nasal drip, swollen nasal passages that cause the nose to feel stuffed, a tickle in the throat that frequently leads to a dry cough, headaches, and itchy, swollen eyes with drainage. Since air purifiers can help reduce the number of airborne contaminant particles in the home, they can effectively reduce the symptoms associated with allergies.

Do Air Purifiers Help with Allergies?

What Causes Airborne Allergy Symptoms?

An individual experiences airborne allergy symptoms when his or her immune system is sensitive to a particular particle in the air. When these particles cause an allergy, they are referred to as allergens.

Which Air Particles Can Cause Allergy Symptoms?

Common airborne allergens include pet hair, pet dander (cat and dog), pollen, fungi spores, mold, tobacco smoke, dust and dust mites.

How Do Air Purifiers Help with Allergies?

An air purifier works by pulling air in via a fan and moving that air through at least one filter. The filter captures the particles and pollutants before pushing the air out the other side into the home.

What Are Air Purifier Filters Made Of?

Filters may consist of fiber (typically fiberglass), paper or mesh. To ensure the purifier remains efficient, filters must be changed or washed according to the manufacturer’s recommendations. These recommendations can be found in the owner’s manual.

What is a High Efficiency Particulate Air Filter (HEPA)?

HEPA filters consist of multi-layered netting that is usually made of very fine fiberglass threads. Since airborne particle sizes vary, in order to capture particles of different sizes, the size of the gaps in these fiberglass threads vary as well.

How Does the Multi-Layered Netting Capture the Allergens?

As the allergens are pulled in by the fan, the particles that are larger than the filter’s fibers are captured when they crash into the fiber. The mid-sized allergens are captured when they touch the fiber. As the ultra-fine particles zigzag through the fibers, they begin hitting the fibers, which allows them to be captured.

How Effective Are Air Purifiers That Have HEPA Filters?

These filters are very effective at removing the ultra-fine airborne particles. These particles include pollen, dust, mold and dander. The industry standard for HEPA air purifying units requires that it be able to remove at least 99.97 percent of airborne particulates that measure 0.3-micron diameter (in the lab).

I Want to Get an Air Purifier, Which One Should I Choose?

Consumer Reports lists the Blueair Classic 605 and  Blueair Blue Pure 211+ (several options available) among the top air purifiers for 2020. Both air purifiers are available on Amazon. The Blueair Classic 605 has more than 400 ratings, with a total star rating of 4 ½ and the group of Blueair Blue Pure 211+ purifiers have more than 800 ratings, with a total star rating of 4 ½.

Once I Have an Air Purifier, Can I Stop Taking My Allergy Medication?

Although an air purifier can help prevent the onset of allergy symptoms, the reason an individual suffers from allergies varies, therefore, an air purifier should never be used as a means to replace other allergy treatments.

Air Purifiers FAQs: Do air purifiers help with dust?

While trees are continually cleaning outdoor air, indoor air needs the help of filters and purifiers to stay unsullied. While air purifiers are excellent at removing pollutants from the air, do air purifiers help with dust? Let’s take a look.

What Is Dust?

Before we can determine whether air purifiers remove dust, it can be helpful to learn what dust is made of. What appears to be a uniform gray substance, dust is actually made up of everything from soil and organic materials to skin cells, food debris, pet dander, and even insect parts. Most of us work to keep our homes dust-free for a variety of reasons, and now we can add the fact that dust is made up of nasty stuff to the list.

Do Air Purifiers Help With Dust?

Along with being a foul substance, dust can also cause respiratory problems and other illnesses, especially for people with existing health conditions and allergies. Reducing the amount of dust in the home is important for your overall health and the appearance of your home, but cleaning dust can be a tedious task.

The good news is that air purifiers are designed to attract and trap dust particles as small as 0.3 microns. For comparison, a single strand of hair is between 100 and 150 microns wide, so air purifiers are picking up most of the tiniest particles floating around our homes and settling on our surfaces. The process is simple, too: as air moves through the filter of an air purifier, these microscopic particles are captured and clean air moves into the living area.

Getting the Best Results

To get the cleanest air in your home, the filter of an air purifier must be changed regularly as a clogged filter will be unable to trap as many particles. A HEPA filter will also help ensure the cleanest air possible as their design is such that 99.97 percent of dust matter is caught. In fact, HEPA filters were designed to trap radioactive material in the air as part of the Manhattan Project so we can certainly trust them to remove most of the contaminants in our home’s air!

The Bottom Line

If you want cleaner air in your home, an air purifier will do the job. For the best results possible, choose a model that has the option for HEPA filters, and breathe easy when you’re at home.

Air Purifiers FAQs: Do Air Purifiers Help With Mold?

When you consider the health and well being of your family, It’s natural to wonder “do air purifiers help with mold?”

Mold spores can cause allergic reactions and illnesses, so you’ll want to inspect and clean your dwelling on a regular basis and free of moisture caused by leaking water.

Air purifiers will not completely solve mold problems all by themselves but they definitely can help with mold: According to the Environmental Protection Agency’s Guide to Air Cleaners in the Home, “Portable air cleaners and furnace/HVAC filters may remove some of the particles generated by mold. In some cases, they may also help reduce odors, but they will not resolve a mold and moisture problem.”

More advanced equipment is used to remove mold. The EPA notes in another edition of its report on air cleaners that ultraviolet germicidal radiation or UVGI cleaners can destroy “molds that are airborne or growing on HVAC surfaces (e.g., found on cooling coils, drain pans or ductwork.”

The air purifying system you install can include in-duct particle removal. As the EPA puts it, “Most mechanical air filters are good at capturing larger airborne particles, such as dust, pollen, dust mite and cockroach allergens, some molds, and animal dander.” Air filters are rated by their minimum efficiency reporting value (MERV) ranging from 1 to 20. The EPA reports that air panels with a MERV of 1-4 can trap some mold spores, so they can provide a useful role in your air purifier setup.

Preventing Mold Growth

Mold tends to grow in moist conditions, so make sure to periodically tour your property, looking for cracks and signs of leaks. Sealing all potential entry points for water also helps keep out the wind, which makes it cheaper to keep your home warm in winter and cool in the summer. If you detect a mold infestation, it would be prudent to contact mold eradication professionals to help take care of the problem safely and efficiently.

Remember to Change Filters on a Regular Basis

It makes sense to use air purifiers inside your home, especially if you have children, elderly people or anyone with a health issue that would be affected by poor air quality. To get the most out of your home air purifier, make sure to read the manufacturer’s recommendation on how often you should change the filter. Then put a reminder in your calendar, just as you would to routinely swap out batteries in your home’s smoke alarms.

Air Purifiers FAQs: Do air purifiers help with smell?

There are many reasons for choosing an air purifier. One of the most common of these is to help address odor issues. There’s a great deal of confusion regarding this subject, largely because there isn’t a simple answer to the question.

The Filter Matters

In order to tease out the true answer regarding the question do air purifiers help with smell, it’s important to understand how they differ from one another. Despite the fact that there are different technologies used to clean and purify the air, the type of filter an air purifier uses is crucial to its effectiveness at removing odors.

How Does an Activated Carbon Filter Work?

An activated carbon filter is designed with a large surface area relative to the air purifier’s volume. This surface area contains a network of submicroscopic pores. These pores are designed to absorb the particles that contribute to odors.

The unique design of an activated carbon filter enables molecules to attract other molecules that are contained within particles. These molecules attach to each other and are then removed.

Which Odors Can an Air Purifier Remove?

When armed with an activated carbon filter, an air purifier is effective at removing a variety of odors including smoke, pets, chemicals, cooking and more.

Depending on the air purifier, it might also be possible to wash the activated carbon filter. Doing so frequently improves the filter’s effectiveness and can increase its lifespan.

Square Footage Matters

Another consideration when searching for an air purifier to remove odors is the size of the area the unit is rated for. Each air purifier states the maximum square footage that it’s capable of.

It’s important to match the size of the room or home with the right size air purifier. Otherwise, the unit won’t be able to purify the air as effectively.

Other Considerations

Regardless of the quality of the air purifier, following all the manufacturer’s recommendations regarding placement, maintenance and capabilities is crucial to its effectiveness. For example, most manufacturers recommend that the casing and under the air purifier be kept clean and free of obstructions. Another common recommendation is a regular schedule of fliter replacement and/or cleaning.
