Aerostar Series 400 Pleated Furnace Air Filter 25x25x1 MERV 10 Standard Capacity

The Aerostar Series 400 pleated furnace air filter provides dependable air filtration with excellent airflow performance for commercial and industrial HVAC applications. Featuring advanced 100% synthetic filter media, this MERV 10 filter captures airborne particles such as dust, pollen, mold spores, dander, and other common irritants while helping maintain cleaner indoor air.

The synthetic media is laminated to an expanded metal support grid on the air-exiting side, providing added strength during installation while preventing pleat fluttering and maintaining uniform airflow. The moisture-resistant heavy-duty frame helps prevent warping, cracking, and distortion during normal operating conditions.

Designed for 25x25x1 HVAC systems, the Aerostar Series 400 filter handles air velocities up to 500 FPM and delivers consistent filtration with low airflow resistance. It is ideal for commercial buildings, schools, offices, industrial facilities, and HVAC applications requiring reliable protection for coils, ductwork, and system components.
