Aerostar 20x20x5 MERV 11 AC Furnace Air Filter, Pleated HVAC Filter, MPR 1000 FPR 7, Allergen Defense, 2-Pack, Made in USA

The Aerostar 20x20x5 MERV 11 pleated air filter delivers reliable home air filtration in a convenient 2 pack. This electrostatically charged furnace filter captures 95 percent of airborne microscopic particles including dust, pollen, pet hair, pet dander, mold spores, lint, dust mites, and fine dust. 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 effective allergy and asthma 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 1000 and Honeywell FPR 7. 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 20x20x5.
