Aerostar Series 400 Pleated Furnace Air Filter 18x24x2 MERV 10 High Capacity

The Aerostar Series 400 pleated furnace air filter provides high-efficiency MERV 10 filtration with excellent airflow for commercial, industrial, and residential HVAC applications. Featuring advanced 100% synthetic filter media, this 18x24x2 filter effectively captures dust, pollen, mold spores, pet dander, and other airborne contaminants while helping protect HVAC equipment.

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

Designed for 18x24x2 HVAC systems, this high-capacity 2-inch filter handles air velocities up to 500 FPM while maintaining low airflow resistance for improved system efficiency and reduced energy consumption. Ideal for commercial buildings, offices, schools, hotels, industrial facilities, and other HVAC applications, it helps keep coils, ductwork, and system components cleaner while improving indoor air quality.
