Say goodbye to allergies and weird smells 👋

best air purifier for pets

Whether you have allergies or just don’t like the feeling of a stray dog hair floating up your nose, it’s probably worth getting an air purifier if you’re living with a pet.

“[Air purifiers] decrease the amount of dander that can cause allergies,” Dr. Antonio DeMarco, a veterinarian and president of medical operations at GoodVets in Kansas City, Missouri, told The Dodo.

We spoke with Dr. DeMarco, who explained why you might want to invest in an air purifier and how to find the best ones.

The best air purifier for pets is one with a HEPA filter, because it can filter out all those allergens. Here are some of our favorites:

What to look for to find the best air purifier for pets

There are a few things you should consider when shopping for an air purifier.

Opt for a HEPA filter

According to Dr. DeMarco, you’re going to want an air purifier with a HEPA filter, because they’re pretty great for dander.

A HEPA filter is a filter that meets specific high-efficiency standards. For a filter to be considered a HEPA filter, it has to be able to capture 99.97 percent of particles that are .3 microns — aka bacteria-level small.

“I would recommend going with a top-brand air filter,” Dr. DeMarco said. “Most filters will say [they’re] made for allergies [or] pets. [They’re] usually more costly, but tend to work better.”

Factor in your room size

Different air purifiers are designed to perform best in different sized rooms, so you’ll have to keep that in mind during your search.

Take note of the square footage of the room you want your air purifier in, and compare that to the optimal room size listed by the manufacturer.

Think about your ideal noise level

Not all air purifiers operate at the same volume, so you’ll want to think about how loud is too loud for your personal preference, especially if you plan on leaving it running while you’re sleeping.

The noise level will be measured by decibels. For reference, 20 decibels is like a whisper from about 5 feet away, 30 decibels is like whispering nearby, and 40 decibels is the same as quiet library sounds. Under 40 decibels is generally a sweet spot for air purifiers, but it depends on your preference!

We rounded up some of the best air purifiers for pet parents. (Bonus: They’ll actually look good in your home, too.)

Best overall: Blueair Blue Pure 211+ HEPA Silent Air Purifier

This air purifier is the best overall because it removes particles down to .1 microns, it’s super quiet (less than 31 decibels), it removes larger particles like pet hair, and it can filter large spaces really quickly — up to a 540-square-foot room within 12.5 minutes (and if you do that math, that means it can go through 2,592 square feet in just an hour). And it’s got a layer of activated carbon to filter out those telltale pet odors.


As an added bonus, the color block design is fun and functional, since the bottom half is actually a machine-washable pre-filter. And when you want to replace it, you can buy other fun colors like gray, pink, blue, yellow and white.
