4-pack of 20×25×4 MERV 11 pleated synthetic furnace filters compatible with AprilAire 1210, 2210, 4200, and similar 4-inch cabinet whole-house air purifiers — at a fraction of OEM AprilAire 213 pricing, with the same MERV 11 allergen-and-pet-defense filtration spec.

This is a generic aftermarket Pack of 4 replacement air filters in the 20×25×4 nominal industry-standard size — compatible with AprilAire whole-house air purifier cabinets that accept 4-inch deep filters: AprilAire 1210, 1620, 2210, 2216, 3210, 4200, plus AprilAire 2120 / 2200 and Space-Gard 2200 cabinets when paired with the AprilAire 1213 Upgrade Kit, plus AprilAire UV12 and UV22 systems. Each filter uses pleated synthetic fiber media rated MERV 11 (Minimum Efficiency Reporting Value 11 per ASHRAE 52.2 standard) — captures airborne dust, pollen, mold spores, bacteria, pet dander, dust mites, smog, and smoke particles as air circulates through your HVAC system. Comparable in filtration performance to MPR 1000-1200 / FPR 7 ratings used by other aftermarket brands (Filterbuy, BNX, Aerostar, Filtrete, AIRx). Replacement frequency 6-12 months depending on usage intensity; 4-pack covers 2-4 years of typical use. NOTE: This is a GENERIC AFTERMARKET product — it is NOT genuine OEM AprilAire, NOT manufactured by AprilAire, NOT covered by AprilAire warranty, and NOT affiliated with Research Products Corporation. AprilAire model numbers referenced solely for fitment compatibility per safe-harbor standard. The AprilAire trademark is the property of Research Products Corporation. Outer retail carton has minor edge tearing in shipping; contents inspected and undamaged. Sold AS-IS with 30-day eBay returns.
