white colored furniture for office for modern look

If you work full-time, then chances are that you spend a good portion of your life at the office. So, it’s important to ensure you have a safe environment to work in. In addition to being free from too much clutter, and having adequate lighting to work in, another very important factor to consider is the indoor air quality within your office space. This is particularly important if working in a small room with a lack of fresh air.

Constantly breathing in dirty or dusty air isn’t good for anyone, particularly those who suffer from allergies or any kind of breathing problems. As well as affecting the way in which you breathe and the way in which you function, inhaling unfiltered air can also increase the risk of spreading harmful viruses. It can also affect productivity levels.

But thankfully, regardless of whether you have a small home office, or you work in part of a big open plan room, there are steps you can take to improve the air you breathe within your office space. One of which is to invest in a good quality air purifier.

In this guide we’ll explore some of the most important factors to consider when buying an air purifier for the office.

This will help you decide what features and functions you’re looking for and will help narrow down your end selection when you do go to buy. Then, we’ll share with you some of the best air purifiers out at the moment for office use. In this section, you’ll find out exactly what each of these top models has to offer and which is best suited to meet your air cleaning requirements.

Best Air Purifiers for Office Use: Buying Guide

Before you head straight out and buy an air purifier on the simple merit that it would look great in the office, there are a few things you should consider first:

  • The size of the office: Before you even take a sneaky peek at any air purifier, you need to know the size of the office you’re looking to filter the air in. This is probably the most important factor as buying a machine that’s not powerful enough is almost as bad as not having one at all. Likewise, buying an air purifier that’s too big for the office space you have, is simply a waste of money. Which brings us nicely on to the next point.
  • Your budget: If you work for a large corporation, this probably won’t be too much of a concern for you as they are likely to be footing the bill. If, however, you work for yourself, or you are the boss, then it’s definitely something you’re going to want to bear in mind. When it comes to price, air purifiers vary massively. However, much of this is linked to the quality of the components and the efficiency of the machine. So, try not to think of the purchasing of an air purifier as just another unnecessary appliance, as it is providing you with better quality air to breathe, which has a huge number of benefits.
  • Usage: Another thing you’ll want to consider is where the air purifier will be used. Is it just to be for one particular office or will it be moved around to various rooms? If you’re purchasing an air purifier to simply sit in one location, then the size or weight of the device won’t really matter, provided there’s enough space for it to work efficiently. If, however, you want an air purifier that you can move from office to office you’ll want to look for a model that’s not too heavy and easy to transport.
  • Space: This is another important factor as not having enough room for your air purifier to be able to work properly is not only ineffective, it’s also unsafe. So, before you make your final decision, and all the other above boxes are ticked, just make sure there is enough space to put it. Somewhere safe enough where it’s not a trip hazard, yet out in the open enough where you get the maximum benefits from it.

The Best Air Purifiers for Pets

a child playing with pets

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

An effective air purifier works by removing harmful irritants and pollutants in the air, such as cigarette smoke, household contaminants, and both large and small particles. Contaminated air is filtered through a complex filtration system and clean air is delivered. The result is fresh air and an odor-free home.

In this article we’ll not only go through some of the things to look for when purchasing an air purifying system for pet allergies, but we’ll also give you the lowdown on some of the best models out at the moment.

Table could not be displayed.

Buying Guide: What to Consider When Buying an Air Purifier

With so many different air purifiers on the market today, it can be daunting to choose the best model for you, particularly if you’re a pet owner. The following section will give you a better idea of some of the most important factors 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 26” in height and 10.5 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 peace 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 similarly to 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 30 minutes. It’s also a very sleek and snazzy looking machine that would look great 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 its 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 the Germ Guardian. It’s a 4-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 6.69” x 27.56”, 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 4-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 HR900

Considered to be the next generation of air purifier, the Winix HR900 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 HR900 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. This ultra quiet setting can be great if you’re easily bothered by noise. 

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 an 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.

Honeywell HFD320 AirGenius 5

Here we have another fantastic air purifier in both looks and functionality. Hosting a smooth, black exterior, the Honeywell HFD320 AirGenius 5 is definitely one of the better looking models out there. It also features some great design qualities. Being tall and slender means you need less floor space to be able to use this device effectively. At 9.9” x 9.7” x 26.8” it can be plonked just about anywhere there’s free-flowing air.

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.

Air Purifiers FAQs: Do Air Purifiers Help with Allergies?

a man suffering from 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.

Do Air Purifiers Remove Dust?

dust on the wood board

Many people believe that air purifiers remove household dust. Perhaps a few people question this since dust particles are tiny particles and because sometimes, the air purifiers may be placed in large rooms. So, in this article, we will help satisfy your curiosity and provide a detailed answer to the question “do air purifiers remove dust?”

For us to properly do this, we have to discuss dust and air purifiers. We also have to look at what air purifiers are best for removing dust if any air purifiers are capable of removing dust particles from large rooms and by so doing, improving air quality.

What is Dust?

Dust is made up of solid particles of various matter forms which may include soil, pollen, human hair, skin cells, pet hair, and several pollutant particles. Many people think that dust is made up almost seclusively of dead or worn-out human cells but this is not true. Yes, human body cells make up a portion of dust in your home and my home but it is not the major constituent of dust. You are more likely to have larger portions of dust from outside soil conveyed by the wind, from dust mites, mold spores, insect-byproducts, and several other sources.

Some dust particles, especially from pollens, mold spores, or such organic particles are less likely to harm you unless you already have a medical condition that makes you allergic or if you are asthmatic. Since dust particles are airborne particles, they are likely to be harmful to people who suffer from allergy symptoms. This is often without warning due to the fact that dust is particulate matter. So, besides the fact that dust settles on the floor and things around the house, making them dirty and unhygienic, you also have to deal with the health effects of dust in the living room, large rooms, and in your home in general.

Dust can affect your respiratory system, triggering health problems. So, it is important to have clean air free of pet dander, mold spores, dust mites, cigarette smoke, and various forms of allergens in your living room and in indoor spaces. This is why air purifiers are important. Air purifiers help in improving air quality by making use of a filtration system to remove indoor dust and produce fresh air for you to breathe. Or do they? We will now look at air purifiers to see if they do this and how they do this- how air purifiers work to remove dust and improve air quality.

How Air Purifiers Can Help Combat Dust

Air purifiers are called air purifiers because they simply purify air to a large extent.

They are devices that help remove mold spores, pet dander, dust particles, and a host of other airborne particles or allergens from indoor air.

They do this by using a filtration system that works to clean air and improve indoor air quality. You need to understand that most of these particles we speak of cannot be seen by the naked human eye. They are so small that they are measured in microns. 1 micron for instance is one part out of a million parts. Yet, some of these particles are smaller than even 0.3microns. Keep in mind that the different particles that make up dust could range from as small as 0.01microns to over 400microns

Air purifiers work in different ways depending on the type of air purifier.

We will now discuss two of the most common types of air purifiers before giving you our verdict on which air purifier is the right air purifier or the most effective at removing dust particles and other airborne particles too.

This will guide you in choosing air purifiers, especially if you are looking for the best air purifiers for dust removal.

Types of Air Purifiers to Remove Dust

Ionizers

Ionizers are also known as ionic air purifiers. They purify the air by passing air through a filtration system that utilizes negatively charged ions to bond to the particles in the air, making them heavier and causing them to drop on the charged collection plate in the air purifier. In this way, ionizers select particles from the air. Ionizers are effective in removing particles from the air and in deactivating germs with their negatively charged ions. However, they are not as good as HEPA air purifiers when it comes to removing particles. They also don’t do anything about the smell in the room.

People are however cautious of Ionizers because of the ozone they produce as by-products. Ozone generators which are an entirely different device make use of ozone in an attempt to eradicate airborne particles. However, it produces a large and unhealthy level of ozone which is really harmful to homeowners and it also does not have collection plates to collect the particles that the ozone binds to, ensuring that the particles are on the floor and can be destabilized into the atmosphere again. Unfortunately, many ozone generator producers pass them off as ionizers, giving ionizers a bad name. Since ionizers produce ozone as by-products, people are skeptical of Ionizers even though the ozone generated is in very little and very safe quantities. So, yes. Ionizers can remove dust from the air. You will have to keep up regular maintenance by regularly cleaning the collection plate though.


HEPA air purifiers

High-efficiency-particulate air purifiers (HEPA air purifiers) is the known best air purifier for dust removal and for removing airborne particles in general. It is built with a technology that ensures that it traps most airborne particles. HEPA air purifiers make use of air filters called HEPA air filters as their filtration system tools. There are two types of HEPA air filters.

True HEPA filter: This is the most efficient filter type. They capture or trap any particle as big as 0.3microns or more. There is a rigorous process used in certifying true HEPA filters to ensure that they meet up with the accepted 99.97% efficiency when it comes to purifying indoor air. This is the best-known air purifier for dust removal.

HEPA-type filter: this is s less effective HEPA filter. It is effective for up to 95%. It is also great or cleaning air and trapping particles but obviously not as good as the True HEPA air purifier.

HEPA air purifiers have to be maintained regularly as well. Maintenance includes filter replacements which will be done from time to time because the filters trap lots of particles and microbes which have to be done away with. When the filters get saturated and are not replaced, you may risk the filters becoming a source or reservoir of the very particles you need to get rid of. The air purifier at that point may even pose more danger than if you had not gotten it. At the end of the day, this applies to lots of devices. They have to be properly maintained so they can function effectively.

There are other air purifiers such as the activated carbon filter air purifier and the UV-C based purifiers. Sometimes, the technologies are mixed or simultaneously employed to both remove dust and to deactivate microbes that may be present in indoor air.

Conclusion

Yes, air purifiers can remove dust from indoor air. This does not mean that air purifiers can remove every single dust particle. They will remove most dust particles. Keep in mind that dust particles range from 0.01microns to about 400microns. Also, HEPA air purifiers for instance can trap anything as big as 0.3microns. Unfortunately, particles as small as 0.01microns will most likely pass through the pores in the HEPA filters. However, you can be sure that most of the particles will be trapped, and only very few can make it through. The best shot you have at purifying the air in your living room or indoor space and getting fresh air that will be free from allergens remains the HEPA air purifiers.

Some air purifiers combine the HEPA air filter technology with the Ionizer technology to ensure that microbes are also killed or deactivated. Ionizers also do a good job of removing dust and microbes from the air. There are a few other types of air purifiers but they do not work as effectively as the HEPA air purifier. So, if removing dust is your goal, we recommend the HEPA air purifier, preferably one with True HEPA filters. A notable mention for removing particles would be the activated carbon air filter which uses carbon filters to remove large particles and organic compounds by filtering them through its pore spaces. It is a good air filtration device but also not as good as the HEPA air purifier with regards to the amount of dust it can filter.

Do Air Purifiers Help With Mold?

mold and moisture damaged the wall of the house

In quick response to the above title, “Do Air Purifiers Help with Mold?”, the answer is yes. If you’d like to know just a touch more about just how effective these devices are when it comes to treating pesky mold spores, then keep reading.

A home doesn’t have to be dirty to have problems with mold. It can appear just about anywhere indoors where you have high temperatures and high humidity levels. If it’s not treated quickly and effectively, mold can cause a whole a range of problems, not just to the house, but to your health as well. But don’t despair as there are steps you can take to help eliminate mold and keep it at bay. One of which is to invest in a decent air purifier.

In this article, we’ll go over in more detail why you need to steer clear of mold and mildew and how to best banish it from your home. We’ll also explain how an air purifier works and how it can help calm this situation, improving your indoor air quality in an instant.

Following on from that, we’ll then point you in the right direction of some of the best air purification systems available now for tackling mold within the home.

Why Mold Needs to be Avoided 

There’s quite a range of adverse effects mold spores can have on your health including the onset of allergies, asthma, chemical sensitivity flares, and respiratory problems. And these are just the short-term effects. Long-term exposure to mold is much more serious. Symptoms related to long-term exposure to mold include cancer, neurotoxicity, hypersensitivity pneumonitis, and pulmonary injury.

Mold spores reproduce by releasing spores into the air. They float around the air until they find a damp surface to cling to. Then, as long as the surface remains damp, the mold spores are fed. And eventually, they start to reproduce. The spreading of mold can happen very rapidly so it’s important to deal with it as soon as it’s detected.

Where Mold is Most Likely to be Lurking 

As mentioned earlier, mold can appear anywhere that’s moist and humid. If the humidity indoors is above 60%, this is the perfect breeding conditions for mold. Finding a large source of mold in the home could indicate a much deeper problem such as poor ventilation or leaking pipes. Whatever the source may be, it still needs to be treated. In worst cases, if mold is left untreated, apart from the damage it could do to your health, it could even cause the decaying of your home.

Quite often, in properties of poor ventilation, mold spores will form around the edge of the window, typically in the corner. In the bathroom, however, you may notice spots of mold appearing just about anywhere. Both the shower and bathtub are very common as these areas tend to be damp quite a lot. The sink and toilet are in the same boat. However, you also need to look closer. Mold is very good at hiding and is also likely to appear in places such as shampoo bottles, shower heads, and toothbrush holders as all offer the perfect conditions for reproducing.

How Air Purifiers Can Help

There are various types of air purifiers available. However, not all of them are effective at mold removal, so you need to be careful. Any air purifier that’s fitted with a True HEPA filter will definitely help as these filtration systems physically trap the mold, preventing them from reentering the atmosphere. Ideally, when dealing with mold, you should also choose a model that’s fitted with an activated carbon filter. These filters are specially designed to tackle odors and are the only kind strong enough to deal with mold.

Another good feature to look for is those fitted with a germicidal UV-C light. These are the most effective at stopping mold spore reproduction. While there is some controversy over whether UV light should be used in air purifiers because of its potential danger to humans, it is contained within the system itself and therefore should eliminate any associated risk. As air passes through, it’s exposed to UV-C light, destroying any mold spores’ DNA, making it impossible for it to reproduce.

While air purifiers won’t completely solve your mold problem, it’s certainly a good place to start. According to the Environmental Protection Agency’s (EPA) Guide to Air Cleaners in the Home,  while both portable air cleaners and HVAC filters may be effective at removing some mold spores, they won’t solve an ongoing mold and moisture issue. To do this, more specialist equipment will be required. But if you’re looking to remove naturally occurring mold spores from your indoor air then an air purifier is a good tool to help.

Preventing Mold Growth 

It’s one thing tackling mold that’s already there, but it’s another thing altogether, preventing it from returning. However, if you want to continue breathing in fresh and uncontaminated air, then both must be adhered to. One way to keep on top of any mold problems within your home is to periodically tour your property looking for cracks in the walls, or any signs of leakages. You should also ensure that all potential entry points for water are sealed. This will also help shield the property from wind, helping to keep your home warmer in the winter.

If you do detect any signs of serious mold, contact the professionals who can treat this problem immediately for you. Once the current problem has been rectified, your air purifier will work much more effectively at providing you with a constant supply of clean air.

When you do have your own air purifier in operation at home, make sure you change the filters on a regular basis, especially if living with any elderly people or those with any underlying health problems. While many of the high-end models have integrated filter replacement monitors, some of the budget models are a little less intuitive and will need to be checked manually every few weeks. If it looks dirty or clogged, then replace it. If you read the manufacturer’s guide, it should give you a better indication of how often the filter will need changing.

Air Purifiers FAQs: Do air purifiers help with smell?

a girl holding her nose from bad 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 are 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 filter replacement and/or cleaning.

What is a Hepa Filter & How Do They Work?

working of hepa filter

While the topic of air pollution is quite a hot one and has been for the past few decades, most conversations that take place focus on the environment and the air quality outside of our homes. However, indoor air quality can be just as bad as that outside, if not worse. The difference is that inside, we have the opportunity to change that via way of a good air filtration system.

If you’ve never owned an air purifier before, and never really read up about them, when you do go to look for one, it can be a little daunting with all the terminology and acronyms like HEPA, MERV, and CADR that are thrown around. In this guide, we hope to put some of those burning questions to bed and explain a little more about what some of these terms refer to.

HEPA-Type Filters Explained 

HEPA stands for High-Efficiency Particulate Air. It’s a kind of filter that’s found in most good air purifiers and vacuum cleaners and is very effective at trapping unwanted airborne particles. However, not all contaminants are captured. Particle size plays a big part here.

Filters that are deemed to meet the HEPA standard are those that are capable of removing 99.97% of all particles that are 0.3 microns or larger in size. Microns refer to the unit of measurement for particles and is the equivalent of one-millionth of a meter. Dust mites tend to be between 1-10 microns in size, although some can be much smaller.

A HEPA filter is made out of a series of pleated fibers. These fibers are often made out of glass fibers (otherwise known as fiberglass) or some kind of polypropylene or polyester non-woven fabric material and are held together in a frame. The most common type of frames used are those made from either plastic or cardboard. Quite often they will also feature a rubber or foam seal in which to prevent air from escaping.

The aim of a HEPA filtration system is to remove both small and large particles from the air. While larger particles such as pet hair and pet dander are a pain, they aren’t usually as harmful to you as smaller contaminants such as bacteria or viruses. And therefore, these are normally taken care of by way of a pre-filter.

Depending on the size of the contaminants, it depends on how it’s trapped. Larger particles are trapped by way of inertial impaction and sieving. These particles either get trapped on their own or they collide with other fibers which then get stuck trying to passing through the fibers. Medium-sized particles are seized by the fibers via interception. While smaller particles are diffused as they pass through the filter.

Air Filter Rating System Explained 

When looking to buy an air purifier, one term you’ll see around a lot is MERV. MERV stands for Minimum Efficiency Reporting Value and is essentially the quickest way to find out how effective an air purifier really is.  It’s a scale that was developed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) back in 1987 and ranges from 1-20. The higher the rating, the less that can pass through it.

Simple dust filters tend to have a MERV rating of around 1-4. And while these are good for filtering out things like human hair and large dust particles, they have very little effect when it comes to removing smaller contaminants. Air filters with a MERV rating between 5-8 are generally your lower end disposal filters. These are slightly better and will filter things such as mold spores, and certain chemicals, they still aren’t very good at dealing with small particles. Air filters with a rating between 9-13 are better, especially when dealing with fumes, but still not really fit for use at home.

Really, when looking for an air purifier to use within the home, you should aim for one that has a MERV rating of 14+. Those that range between MERV 14-16 are capable of filtering up to 95% of particles 0.3 microns or larger. Which is not bad. They’re good for eliminating small and medium particles, as well as dust and mold spores. And, they’re good for anyone who suffers with low-moderate allergies.

However, if you’re someone who suffers from any high levels of allergies or any breathing conditions such as asthma or COPD, you should be looking to invest in an air purifier that has the best level of effectiveness. In which case you need to be looking at either a true HEPA filter or a ULPA filter.

A true HEPA filter has a MERV rating of 17+ and is the most common type used in air purifiers today. These filters are good for allergens and are very effective at removing mold spores, pollen, dust mites, and other microscopic contaminants. A ULPA (ultra-low particulate air) filter is the highest rated of them all and has a MERV rating of 18+. A filter of this caliber can remove even the smallest of particles with the greatest of efficiency. However, these filters don’t come cheap and are often only found in places such as clean rooms or biosafety cabinets.

Are HEPA Filters Washable? 

Yes….., some of them.

As you can probably imagine, HEPA air filters come in all kinds of shapes and sizes. In addition to that, they also vary in whether or not they are washable. Both the washable and washable types have their pros and cons, some of which we’ll go through here.

Washable HEPA filters

These consist of thick fibers that have been designed to get wet. The benefit of using these filters is you can wash them as often as you’d like and they will last quite a long time. However, just be aware that the more they are washed, the less effective they will become. So, while you want to make sure they stay clean enough to do the job, you don’t want to put more wear into them than needed. The other downside is the hassle of removing the filter, giving it a clean down and a rinse, and popping it back in your device.

Non-washable HEPA filters

While you will no doubt spend more money when using non-washable HEPA filters, they do have their advantages. The first is that you don’t need to keep scrubbing them, and they will still last a very long time. However, you can prolong their life a little longer by giving them a quick vacuum every now and then. And while it is still a bit of a pain having to remove the filter, at least there’s no scrubbing involved as there is with the washable kind.

Things to Consider Before Buying a HEPA Filter

You should now that you have a pretty good understanding of how HEPA filters work and why they’re so effective. So, in this section, we’ll go through some of the things to consider before making your next HEPA filter purchase:

Room Size

Before you part with any money, the most important factor to consider when buying an air purifier is whether or not it will be effective in the space you want to place it. Once you’ve decided on where it’s going, the next step is to get the room’s measurements. Any air purifier that’s worth investing in, will tell you the maximum room size it’s capable of filtering. Never buy an air purifier that’s too powerful for the room it’s going as is just a waste of energy. On the flip side, don’t get one that can’t handle the size of the room it’s going in.

CADR

Another factor to bear in mind is the air purifier’s Clean Air Delivery Rate (CADR). This metric was developed by the Association of Home Appliance Manufacturers (AHAM) and essentially refers to the volume of filtered air a device can deliver. It is only ever measured in the highest fan speed but is a good indication as to how much filtered air you’ll get. The CADR scale ranges from 0-450 and is measured in cubic feet per minute (CFM). However, any air purifier with a CADR rating of less than around 300, really isn’t worth its money. Just remember that the higher the CADR rating, the more powerful the fans are.

Activated Carbon Filter

While HEPA filters are exceptionally good at removing contaminants from the air, they’re not very good at tackling odors. Therefore, a lot of good quality HEPA filters are used in conjunction with activated carbon filters. These filters were designed specifically to remove gas and odors from the air. And while they don’t make any real difference in terms of dealing with larger airborne particles, they are fantastic when it comes to filtering out cigarette smoke, mold spores, or even those lingering pet smells.

UV-C Light

There is a wide range of air purifiers on the market today, all varying in performance, budget, and features and functions. And while many of these are just added extras to enhance the user experience, one feature that is thought to make a difference is the addition of a UV-C light. When used correctly, this form of ultraviolet light can be very effective in killing germs, mold, bacteria, and more. The downside is that UV-C light is the most dangerous form for humans and other living organisms.

It works by destroying the nucleic acids in cells, and as a result, disrupts the DNA. This causes the cell to become incapacitated or die. Air purifiers that use UV-C lights first draw the air in through a filter of some kind. Then, as air passes through the purifier’s chamber it’s subjected to the UV light. With a design such as this, there’s no releasing of the UV light into the room, so exposure is prohibited.

We hope you found the above useful. There isn’t really much to HEPA filters when you break it down. But as simple as they are, they are highly effective air cleaning machines that require very little maintenance other than a replacement filter every now and then. You can pick a decent one up for less than $200, and once you’ve got one, you’ll never look back as you sit back, relax, and breathe in air cleaner than you ever have!
