Our 18"x20"x1" HVAC fireplace air filter—available in MERV 9, MERV 11, and MERV 13 ratings—is your preferred choice for crafting a healthier indoor environment. Boasting actual dimensions of 17.75"x19.75"x0.75", it offers universal compatibility, seamlessly fitting both residential and commercial HVAC systems to ensure hassle-free use with nearly all major brands.
Setting itself apart from leading brands like 3M Filtrete MPR 600, Filterbuy AFB Silver, and Honeywell FPR 5, our filter goes beyond basic filtration: it generates negative oxygen ions, breaks down formaldehyde, and traps airborne particles (including dust, pet dander, lint, and pollen)—all to deliver crisp, clean indoor air.
Crafted with advanced pleat technology (featuring a higher pleat count than most retail filters), it boosts both airflow and filtration efficiency for reliable performance. Manufactured in China to premium standards with meticulous attention to detail, the filter is ideal for both residential and commercial settings and maintains peak effectiveness for up to 3 months.
Installation and replacement are a breeze: whether for air conditioners, furnaces, heat pumps, or HVAC systems, just slide it into the slot or fit it into the return air grille (follow the airflow arrow)—and you’re finished!
