Best independently tested and certified air purifiers

If you live in wildfire territory, or a smoggy city, you might feel that the air inside your house is cleaner, or safer than the air outside. However, the truth might surprise you: According to the Environmental Protection Agency, the air inside your home can be more polluted than the air outside. Air purifiers, which filter particles from the air, can help reduce indoor air contaminants that arise from everyday life.Get more news about home air filter,you can vist our website!

Air purifiers are designed to remove indoor air pollution from cooking, car emissions, or dust from wildfires, among other contaminants. These airborne particles enter your lungs, causing irritation or triggering allergic reactions, explained Kenneth Mendez, president of the nonprofit Asthma and Allergy Foundation of America. To help guide your search for an air purifier that best suits your needs and budget, we consulted health and filtration experts to learn more about air purifiers and what you need to know before buying one.

Experts agree that filtration is key when choosing an air purifier. There are two standards and testing procedures, HEPA and CADR, that help show how efficiently air purifiers clear the air in a room.

High-efficiency particulate air (HEPA) filters: Every expert we spoke to agreed that HEPA is crucial for filtration, but HEPA isn’t a centrally regulated standard, so shopping for these filters can be complicated. That’s why experts recommend you shop for HEPA-level filtration and note each air purifier’s clean air delivery rate (CADR) which gives you more information about how well an air purifier will clear a given space of contaminants (including tobacco smoke, dust and pollen), its primary purpose. You can learn more about HEPA filters here.
Clean air delivery rating, or CADR: The Association of Home Appliance Manufacturers (AHAM) works with independent laboratories to certify air purifiers that meet its standards. CADR tells you how much air (in cubic feet per minute) an air purifier can process within one minute. According to AHAM, your air purifier should have a CADR rating equivalent to about two-thirds the area of your space (in square feet). For more on HEPA and CADR, see our primer on HEPA and CADR filtration testing.

Since we don’t test air purifiers ourselves, we rely on expert guidance to recommend the best air purifiers. Aligning with that guidance, the air purifiers below are AHAM-approved and/or recommended by Consumer Reports. For each purifier, we list its capacity and efficiency rates, according to AHAM testing. We ordered them by their capacity in square feet.

Blueair Classic 605
In Consumer Reports testing, this air purifier was one of only four models tested that scored an “Excellent” for removing particles at both the highest and lowest speeds. The purifier uses the brand’s HEPASilent technology, which Blueair says can filter 99.97 percent of particles down to 0.1 microns. You can also control settings from the companion Blueair app or from an Alexa device with voice control.
