Compact or box style filters are used in HVAC applications as high-efficiency final filters in industrial, commercial, medical and institutional applications and as prefilters in HEPA installations.
Compact filters are used in HVAC applications as high-efficiency filters in industrial, commercial, medical and institutional applications to improve indoor air quality and comfort. The filters in the supply air are used as second filter stages or as prefilters for cleanroom process applications. The filters are also used in the exhaust air or in recirculation systems to protect the air handling units and provide improved air quality. Compact filters are not subject to varying HVAC system airflow and some are designed for turbulent air applications.
