Air quality matters. That's why you trust AprilAire to keep your home environment safe for you and your family. This genuine AprilAire 501 Air Filter makes the air in your home fresh and healthy so your family can breathe easy. It's proven to capture 98% of particles between 3.0 and 10.0 microns from passing through your home's heating and cooling system. That includes dust， pollen， and mold spores， which can irritate allergies and worsen asthma symptoms. Annual air filter replacements are a great way to keep your home and family protected. 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.
