Air Purifiers

A HEPA air purifier traps particles in a physical filter, while an ionic air purifier releases charged ions that help airborne particles cluster together and settle or collect. A true HEPA filter is rated to capture 99.97% of particles 0.3 microns in size. HEPA filters need periodic replacement, while many ionic models are filterless and lower maintenance. Compare HEPA Air Purifiers and Ionic Air Purifiers.

Choose an air purifier rated for a room at least as large as the space you want to clean. Coverage is usually listed in square feet. A model like the 250 Sq. Ft. Air Purifier with UV Technology fits a bedroom or home office. The 2520 Sq. Ft. Electrostatic Precipitator HEPA Air Purifier is built for large, open living areas. If you’re between sizes, go one size up for faster results.

Air purifiers can help reduce airborne allergens like pollen, dust, and pet dander, which may make rooms more comfortable for allergy sufferers. They work best alongside regular cleaning, since they only capture particles in the air, not on floors or furniture. Placing one in the bedroom, where you spend the most hours, is a good place to start. Find more options in Allergy Solutions.

Most air purifier filters need replacing every 6 to 12 months, depending on the model, how often you run it, and the air quality in your home. Check your product manual for the recommended schedule. Running it with a clogged filter reduces performance. Find replacement HEPA filters, UV bulbs, and capsule refills in Air Purifier Filters & Accessories.

Personal and wearable air purifiers are designed to clean the small area of air right around you, not a whole room. That makes them useful at a desk, in the car, or while traveling. The Wearable HEPA Air Purifier uses a HEPA filter you can wear on the go, and the Personal Space Air Purifier sits on a desk or table. For full-room coverage, choose a room-sized model instead.
