The Aprilaire Clean Home Filter is the perfect addition to your clean home tool kit. It traps airborne dust as air it circulates through the filter– reducing your cleaning time and frequency, and allows you to enjoy your clean home even more. The 210 Clean Air 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.
