Aerostar Series 400 Pleated Furnace Air Filter 24x24x4 MERV 10 High Capacity

The Aerostar Series 400 pleated furnace air filter delivers high-capacity MERV 10 filtration for commercial and industrial HVAC systems. Featuring advanced 100% synthetic media, this 24x24x4 filter effectively captures dust, pollen, mold spores, pet dander, and other airborne contaminants while helping protect HVAC equipment and maintain efficient airflow.

The synthetic filter 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 consistent pleat structure. The heavy-duty, moisture-resistant die-cut frame helps prevent warping, cracking, and distortion under normal operating conditions.

Designed for 24x24x4 HVAC applications, the Aerostar Series 400 MERV 10 high-capacity filter handles air velocities up to 625 FPM while maintaining low resistance to airflow. It is ideal for commercial buildings, schools, offices, industrial facilities, and HVAC systems requiring dependable filtration to protect coils, ductwork, and other system components.
