Are you bothered by the amount of dust and other particles in the air and on the furniture in your home? The AprilAire Healthy Air 11 traps airborne dust as air circulates through the filter, reducing your cleaning time and frequency. Our Healthy Air 11 air filter protects your HVAC system from airborne particles too, which helps lower your energy costs, and can prolong the lifetime of your equipment. Genuine AprilAire filters are specifically engineered to work with your AprilAire air cleaner. They are effective for 6-12 months compared to the traditional 1-3 month filter, saving you time and money. Our 4-inch filters provide more filter area for harmful particles to be captured compared to the traditional 1-inch filters. AprilAire's patented self-seal technology assures no air will pass by unfiltered, keeping your home clean and HVAC system operating at peak performance.
