The Best Air Purifiers for 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.

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.


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 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 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.
