We put 38 of the best air purifiers through a series of tests in our Lab, assessing them based on their design, noise levels, features, effectiveness, and overall value. For expert tips on buying and using air purifiers we spoke with Kenneth Mendez, CEO and president of the Asthma and Allergy Foundation of America, and Dr. John McKeon, CEO of Allergy Standards.
“People spend more than 90 percent of their time indoors, and indoor air can be two to five times more polluted than outdoor air,” says Mendez. “Indoor air is made up of tiny particles—including animal dander, pollen, mold, dust mites, and fumes released by cooking, burning fuel, or cleaning products—that can trigger asthma and allergies. Air purifiers can improve your home’s indoor air quality by reducing indoor air pollution or removing airborne allergens.”
