Are you bothered by the amount of dust and other particles in the air and on the furniture in your home? The AprilAire 210 Healthy Air 11 Filter is the perfect addition to your clean home tool kit. The 210 Filter traps airborne pollen, mold spores, bacteria, pet dander and dust particles as air circulates through the filter – reducing your cleaning time and frequency, and allowing you to enjoy your clean home even more.

This replacement whole-home filter is rated MERV 11 which means it traps airborne impurities as they pass through the filter that would otherwise float through the air and eventually settle on your furniture and flooring. Your HVAC system is protected from airborne particles too, which helps lower your energy costs, and can prolong the life of your equipment. Lengthen your HVAC system’s life and improve your home’s energy-efficiency by reducing dust buildup.

Genuine AprilAire filters are specifically engineered to work with your AprilAire air cleaner and come with the Pure Fit Promise ensuring that the filter will fit your AprilAire air purifier equipment exactly. Efficient home and system protection – extremely low initial resistance and high dust holding capacity support up to 12 month filter life, saving you time on furnace filter changes compared to traditional 1-3 month filters.

AprilAire 4-inch filters provide superior filter area (28 square feet of filtering media) for harmful particles to be captured compared to common 1-inch filters. The patented Self-Seal Technology assures no air will pass by unfiltered, keeping your home clean and HVAC system operating at peak performance.

The AprilAire 210 Healthy Air 11 Filter has a nominal air filter size of 20 x 25 x 4 inches and is compatible with AprilAire Air Cleaner Models 1210, 1620, 2120, 2200, 2210, 2216, 3210, 4200, or Space-Gard 2200 with Upgrade Kit 1213. The AprilAire Patented Interlock Rail System means no assembly required – easy and quick three-step filter replacement process. Illustrated packaging includes detailed air filter replacement instructions. Designed and made in the USA and backed by the AprilAire Clean Coil Commitment.
