Aerostar Series 400 Pleated Furnace Air Filter 12x20x1 MERV 10 High Capacity

The Aerostar Series 400 pleated furnace air filter delivers high-capacity filtration performance with excellent airflow efficiency 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 contaminants while helping improve indoor air quality.

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

Designed for 12x20x1 HVAC systems, the Aerostar Series 400 high-capacity filter handles air velocities up to 500 FPM while maintaining low airflow resistance. It is ideal for commercial buildings, schools, offices, industrial facilities, and applications requiring enhanced filtration to protect HVAC coils, ductwork, and equipment.
