For Your Pet, The Best Air Purifier For Pets

Even if we are prone to pet allergies, not everyone can (or wants) a hypoallergenic dog breed. Pet dander isn't the only allergen that your dog or cat brings into the house.

They may bring in pollen, dirt, germs, and untold grime from the streets if they spend any time outside.

While a quick wipe down of their paws with a wet cloth can help, an air purifier is the way to go if you really want to keep your home—and the air you (and your pet because they, too, can have allergies, Brachycephalic breed-prone snoring, and pet asthma!) breathe—as clean as possible.

When shopping for an air purifier, choose one that has enough capacity for the size of the room where you'll be using it.

Most models specify a recommended room size, which can range from 150 square feet to 1,000 square feet or more.

You should also consider whether you require any additional features, such as odor control, sleep mode, or air quality indicator lights.

It's also a good idea to keep an ear out for how loud the machine is when it's turned on. Some air purifiers emit white or pink noise that is meant to lull you to sleep, while others are quite loud.

BestForPets (bestforpets.org) has compiled a list of the best air purifier for pets owners.


Honeywell Insight HPA5300B HEPA Air Purifier is the best overall



Stores are struggling to keep the recently launched Honeywell HEPA InSight Series in stock due to its powerful HEPA filtration.

Why? It circulates and cleans the air in rooms up to 500 square feet five times per hour, removing up to 99.7 percent of even the smallest microscopic allergens (looking at you, pet dander) as well as certain airborne viruses, bacteria, and mold spores.

Pet odors will be captured and absorbed when used in conjunction with the Honeywell Enhanced Pet Odor Reducing Air Purifier Filter (sold separately, view at Walmart), which is loaded with activated carbon and zeolite. We only wish the air purifier was available in white as well as black.


Alen Breathesmart Classic Pet Dander/Odor Eliminator is the best splurge



While most air purifiers only remove pet dander, the Alen Breathesmart Classic claims to remove pet fur from the air as well, potentially preventing it from landing on your furniture, carpet, and clothing.

We’re inclined to believe them, given that this beauty was designed by NASA airflow engineers.

You’ll definitely get your money’s worth with a medical grade H13 True HEPA layer that removes 99.99 percent of airborne particles larger than 0.1 micron (most other air purifiers only remove particles larger than 0.3 micron), including dander, bacteria, and aerosolized viruses.

Even though it cleans the air in a room up to 1,100 square feet every 30 minutes, it is extremely quiet.

We also like the air quality sensor light, which is easy to read from across the room and comes in eight different finishes.


Bissell MyAir Personal Air Purifier is the best for odors



This Bissell MyAir purifier not only removes pet dander and other small particles from the air, but it also works to remove pet odors thanks to an activated carbon filter (along with cooking and smoke odors, too).

It has three fan speeds and runs fairly quietly even on high, or set it to “sleep” at night to activate the whisper-quiet mode. There’s even a soft night light.

The small, portable unit moves the air 5 times per hour in rooms up to 100 square feet. Set it next to your dog’s crate or bed, or next to your cat’s litter box, to eliminate odors as close to the source as possible.


Lasko Pure Platinum Slim Profile Air Purifier with HEPA-Type Filtration and Auto Clean is the best choice for allergy sufferers



You can be confident that the air you breathe in your home is clean thanks to its air quality sensor, auto-clean function, and three-stage filtration.

This small HEPA air purifier eliminates pet dander, dust, and other common allergens from the air you breathe.

It also has a carbon filter for odor removal and a UV-A light to combat mold, bacteria, and viruses. Its slim silhouette is appealing, and it is suitable for rooms up to 160 square feet.


Best for Small Spaces: LEVOIT LV-H132 True HEPA Compact Air Purifier



The Levoit LV-H132 Air Purifier will only take up a small space on your bedside table or desk in small rooms where space is at a premium—its base is 8.5 inches around.

Its HEPA filter screens pet dander, pollen, mold, and other dog and cat allergens four times per hour in a space up to 129 square feet using a three-stage filtration process.

Even on high speed, it’s quiet enough to sleep through, and it has a sleek design that looks good anywhere you put it.

The only drawback to this low-cost unit is that it can be difficult to tell if it is working.

What to Look for When Purchasing an Air Purifier


Some air purifiers are more powerful than others, and how much power you’ll need will depend on the size of the room, the number of pets you have, and whether or not your family members suffer from allergies.

Check the coverage area to ensure it meets your requirements.



Aside from cleaning the air, some air purifiers have additional features such as odor and temperature control.

If the air filter is going to be visible, you should think about how it looks. Some are available in a variety of colors, allowing you to match them to your existing decor.



While some people enjoy the white-noise hum of standard air purifiers, others find it irritating.

Fortunately, there are ultra-quiet machines available, as well as those that allow you to adjust the volume.

Some models allow you to program runs to operate at different volumes at different times of day.


How do air purifiers function?

Most air purifiers clean the air in one of three ways, and some use all three modes:

  • High-efficiency particulate air (HEPA) filters are pleated mechanical filters that remove pet dander, dust, pollen, mold, bacteria, and other airborne particles by forcing air through a very fine mesh. The gold standard is HEPA filters.
  • Activated carbon filters absorb odors in the air and remove them.
  • UV filters: These use light to render germs and bacteria inactive. They’re frequently used in tandem with HEPA filters.


Do air purifiers help with pet dander?

An air purifier with a HEPA filter is your best bet for removing pet dander. It cleans the air by filtering out particles as small as 0.3 microns. 

Pet dander is typically 5 to 10 microns in size, so HEPA filters are effective at removing it from the air.


Do air purifiers get rid of dog or cat hair?

If you have pet hair in your room, HEPA filters can remove it.

Unfortunately, as most pet owners are aware, that hair is more likely to become entangled in your clothing, bedding, carpet, or sofa.

That is why you should still consider purchasing pet hair removers.


What is the best location for your air purifier?

The more effective air purifiers are, the closer they are to the source of the pollutant.

In the case of your dog, keep it close to their bed, crate, or wherever they spend the majority of their time.

Do you have a cat? Put it near their litter box to help clear the air of unpleasant odors.


How do you keep an air purifier in good working order?

Always follow the instructions in your air purifier’s owner’s manual. Some have reusable or permanent filters that can be vacuumed or washed with soap and water.

Others have replaceable air purifiers that need to be replaced every few months. If your air purifier has a special light that indicates when it’s time to replace the filter, keep an eye on it after three months of use.
