Aerostar Series 1100 Pleated Furnace Air Filter 20x20x2 MERV 11

The Aerostar Series 1100 pleated furnace air filter provides reliable MERV 11 filtration for residential, commercial, and industrial HVAC applications. Featuring advanced 100% synthetic media, this 20x20x2 filter effectively captures dust, pollen, mold spores, pet dander, and other airborne contaminants while maintaining efficient airflow and protecting HVAC equipment.

The synthetic filter media is laminated to an expanded metal support grid on the air-exiting side, preventing pleat fluttering and maintaining consistent pleat structure for reliable performance. The heavy-duty, moisture-resistant frame helps prevent warping, cracking, and distortion, while the bonded filter pack minimizes air bypass for improved filtration efficiency.

Designed for 20x20x2 HVAC systems, the Aerostar Series 1100 MERV 11 filter handles air velocities up to 500 FPM and provides long-lasting filtration with low initial pressure drop. Its rigid construction and deep pleat design help extend service life, making it an excellent choice for homes, offices, schools, commercial buildings, and industrial facilities.
