We can’t see them, but many irritants lurk in our air. From urban pollution to wildfire smoke to allergens like pet dander, dust and pollen, a lot is getting between our nose and lungs and an actual fresh breath of air, which is why air purifiers have become increasingly popular for in-home use.

Air purifiers feature HEPA or HEPA-type filters to trap teeny tiny particles that we can’t see, plus some of the pet hair and dust bunnies we can see. By pulling these particles out of the air, we get exposed to fewer pollutants, allergens and other airborne particles that can interfere with our senses. In addition to particles, many air purifiers feature a carbon filtration system that can trap odors from pets, cooking, gases and smoke to keep the air feeling fresh and clean.
The best air purifiers have strong enough filters to refresh the air, plus a large enough CADR (Clean Air Delivery Rate) rating to cover your space’s square footage.
To help you find the right air purifier for your household's needs, here are our top picks from leading brands like Airdoctor, Molekule, Blueair and more.
