The Aerostar 14x20x1 MERV 6 pleated air filter delivers reliable home air filtration in a convenient 12 pack. This electrostatically charged furnace filter captures common airborne particles including dust, pollen, lint, and dust mites. Designed as a direct replacement for standard 1-inch furnace filters, air conditioner filters, heater filters, and HVAC vent filters, each filter provides 90 days of cleaner indoor air quality and basic allergy relief. The heavy-duty moisture-resistant frame with reinforced pleats prevents filter collapse and air bypass while maintaining low air flow resistance for energy efficient operation. More effective than standard fiberglass filters. Compatible with Carrier, Bryant, Trane, Lennox, Rheem, Goodman, York, Ruud, and Honeywell central air and forced air heating systems. Comparable to Filtrete MPR 300 and Honeywell FPR 4. Proudly made in the USA with premium materials in American facilities under strict quality control standards. Replace every 3 months, or sooner in homes with pets or smokers, to protect your HVAC system and maintain optimal air quality. Nominal size 14x20x1.
