The 8 Best Air Purifiers for Pet Owners of 2021

Best Overall: Honeywell InsightTM HPA5300B 500 Sq. Ft. HEPA Air Purifier

Buy On Best Buy Buy On Kohls.com

Stores can barely keep the recently launched Honeywell Hepa InSight Series in stock; its powerful HEPA filtration is that good. Why? It circulates and cleans the air five times every hour in rooms up to 500 square feet, removing up to 99.7 percent of even the tiniest microscopic allergens (looking at you, pet dander) and reduces up to 99.9 percent of certain airborne viruses, bacteria, and mold spores.

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, pet odors will be captured, absorbed, and disappear up to 3.5 times more quickly. We only wish the air purifier came in white in addition to black.

Best Budget: Hamilton Beach TrueAir Compact Pet Air Purifier

Buy On Amazon Buy On Office Depot

The small but mighty Hamilton Beach TrueAir Compact Pet Air Purifier is affordable to start with, plus it comes with a reusable, permanent filter (simply vacuum to clean), making it a doubly smart buy for the money. The air purifier has three different speed settings to meet your needs and the HEPA-grade filter captures 99.97 percent of pet dander, along with dust mites and pollen.

It also comes with two replaceable carbon zeolite filters to eliminate pet odors. It works for rooms up to 140 square feet and can be set horizontally or vertically to fit in any space.

Best Splurge: Alen Breathesmart Classic Pet Dander/Odor

While most air purifiers work on pet dander only, the Alen Breathesmart Classic claims to also filter out pet fur from the air, potentially preventing it from landing on your furniture, carpet, and clothing. Given that this beauty is designed by NASA airflow engineers, we’re inclined to believe them. Outfitted 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 microns), including dander, bacteria, and aerosolized viruses, you’ll definitely get your money’s worth.

It’s super quiet even as it cleans the air in a room up to 1,100 square feet every 30 minutes. We also like the air quality sensor light that’s easy to read from across the room and that it comes in your choice of eight finishes.

Best for Odors: Bissell MyAir Personal Air Purifier

This Bissell Myair purifier doesn’t just clear pet dander and other small particles from the air, with an activated carbon filter, it also works to remove pet odors (along with cooking and smoke odors, too). It has three levels of fan speeds and runs fairly quietly even on high, or set it to “sleep” at nighttime to engage its whisper-quiet mode. It even has a soft night light.

The small, portable unit works in rooms up to 300 square feet and moves the air 1.5 times every hour. Set it right next to your dog’s crate or bed or cat’s litter box to stop the odors as close to the source as possible.

Best for Allergies: Lasko Pure Platinum Slim Profile Air Purifier with HEPA-Type Filtration and Auto Clean

Buy On Amazon Buy On Home Depot

With its air quality sensor, auto-clean function, and three-stage filtration, you can rest assured that the air you’re breathing in your home is clean. This small HEPA air purifier removes pet dander, dust, and other common allergens from the air around you preventing them from getting into your nose or eyes where they can trigger an allergic reaction.

It also has a carbon filter to remove odors from the air and a UV-A light to tackle mold, bacteria, and viruses. Its slim silhouette looks attractive and it works for rooms up to 160 square feet.

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

Buy On Amazon Buy On Walmart

In small rooms where space is at a premium, the Levoit LV-H132 Air Purifier will only take up a small space on your bedside table or desk—it’s base is 8.5 inches around. Using a three-stage filtration process, its HEPA filter screens pet dander, pollen, mold, and other allergens four times per hour in a space that’s up to 129 square feet. It’s quiet-enough to sleep through, even on high speed, and has a sleek design that looks attractive anywhere you place it. The only downside to this affordable unit is that it can be hard to tell if it’s working.

Best for Large Rooms: Coway Airmega 400 Smart Air Purifier

Buy On Amazon Buy On Walmart Buy On Home Depot

If your HVAC wasn’t installed with an air-filter or you live in a larger apartment, it’s worth investing in a powerful air purifier like this Coway Airmega that’s designed to filter up to 1,560 square feet. This Energy Star rated air filter uses a True HEPA filter along with activated carbon to both capture and reduce pet dander and other particles up to 0.3 micron while reducing odor.

It comes with a washable and permanent pre-filter. With a brightly colored LED ring that changes color based on the air quality, you’ll always know how clean your air is. It has five fan modes, and the sound of the strongest is equivalent to the noise in a library, meaning it’s pretty darn quiet.
