Aerostar Series 400 Pleated Furnace Air Filter 16x25x4 MERV 8 Standard Capacity

The Aerostar Series 400 pleated furnace air filter is designed to improve indoor air quality while maintaining efficient airflow throughout your HVAC system. Made with advanced 100% synthetic filter media, it effectively captures airborne particles such as dust, pollen, mold spores, lint, and pet dander to help create a cleaner and healthier indoor environment.

Featuring a MERV 8 efficiency rating, this 4-inch pleated air filter offers increased dust-holding capacity and extended service life compared to standard 1-inch filters. Its low airflow resistance helps maintain HVAC efficiency while protecting coils, ductwork, and other system components from dust and debris buildup.

Ideal for residential, commercial, and light industrial HVAC applications, this 16x25x4 furnace filter is designed to handle higher airflow rates and should be replaced according to system usage, indoor air quality, and environmental conditions such as pets, allergies, and seasonal dust levels.
