An air purifier can be useful for any pet owner—especially for cats and dogs.
But to be considered one of the best air purifiers for pet dander, it has to be powerful enough to clean the air of pet hair, dander, and odors; all of which you’ll find in each of our picks.
“Buying the best air purifier for pet dander, hair, and odors can make any room in your home feel fresh and clean no matter how many cats, dogs, or other pets you have in the house,” says Patrick Holmes, Senior Air Quality & Comfort Specialist at Home Air Guides. “Our goal here is to give you the most in-depth research and reviews on the top brands of pet air purifiers so you have everything you need to create a better environment that both you and your animals can enjoy.”

Area Coverage (Size)
Pet dander can travel far, so your air purifier’s area of coverage matters. If the air purifier has a square footage rating that’s equal to (=) or greater than (>) the intended room size, then it’s a good choice. If not, you’ll waste your money buying it. For best practice, you want an air purifier that has a 20% higher area coverage than the room you’re going to use it in.
For a single room, measure the width and length of the space in feet and multiply these numbers together to get the total square footage. For example, a 10′ x 20′ room = 200 sq. ft.
For multiple connected rooms, like a living room, dining room, and kitchen, the only additional step you have to do is combine the total square footage numbers from each space. For example, a 10′ x 20′ living room = 200 sq. ft., a 10′ x 10′ dining room = 100 sq. ft., and a 15′ x 20′ kitchen = 300 sq. ft. Combining these totals together (200 + 100 + 300) equals 600 sq. ft.
This filter captures the largest particles (such as pet dander, hair, and dirt) and helps extend the life of the other internal filters. A pre-filter air filter is usually washable and reusable for the life of the product. The Veva 9000 model above has the best affordable filter system we found in our testing.
Air purifiers can have anywhere between 2-5 fan speed settings, ranging from low to high and anywhere in between. Some even include a turbo speed to speed up the air cleaning process on demand. A good air purifier will not only have a variety of speeds but will remain quiet through all of them so your dog or cat doesn’t get too suspicious.
Unless you’re only dog/cat-sitting for a few weeks, you should be interested in your air purifier’s warranty. Before purchasing an air purifier, it’s recommended that you look at the manufacturer’s warranty. This can help avoid potential problems in the long run. Find out what parts are covered and for what length of time, just in case they do become defective.
An air purifier is a long-term investment and is not something you want to keep replacing. You don’t want to buy a product that becomes faulty and then find out that the warranty didn’t cover the important mechanisms of the product or that it didn’t last for a reasonable period of time.
