Aerostar Series 1100 Pleated Furnace Air Filter 20x25x1 MERV 11

The Aerostar Series 1100 pleated furnace air filter is designed to deliver superior indoor air quality while maintaining efficient airflow throughout your HVAC system. Constructed with advanced 100% synthetic filter media, this MERV 11 filter captures fine airborne particles including dust, pollen, mold spores, pet dander, and other common allergens for cleaner, healthier air.

Engineered for high-performance filtration, the Series 1100 features a durable expanded metal support grid and a heavy-duty moisture-resistant frame that helps prevent air bypass and maintains pleat stability. Its deep pleated design increases dust-holding capacity, extends filter life, and provides low initial pressure drop for improved HVAC efficiency.

Ideal for residential, commercial, and light industrial HVAC systems, this 20x25x1 MERV 11 furnace filter offers enhanced filtration while protecting coils, ductwork, and other HVAC components from dust buildup. Replace every 1 to 3 months depending on system usage, indoor air quality, and environmental conditions.
