Our 20x24x4 MERV 11 A/C furnace filters provide a combination of efficiency, economy, and excellent overall performance. The MERV 11 air filters are an exceptional choice in applications where filter change schedules are based on preventive maintenance schedules and guarding your environments from harmful airborne particles. Removing these airborne particles can help improve allergies and alleviate sinus irritation that can cause watery eyes, itchy throat, coughing, and sneezing. Aside from the health benefits, these HVAC filters will also extend the life of your heating and cooling system by making it work more efficiently.
