The Nonwoven Pocket Filter is a high-capacity medium-efficiency air filter designed for HVAC systems, air handling units (AHUs), and industrial ventilation applications. Manufactured with progressive-density synthetic fiber media and ultrasonic welded pocket construction, it delivers excellent dust-holding capacity, low pressure drop, and stable airflow performance.
Available in G4, M5, M6, F7, F8, and F9 efficiency grades, it provides reliable protection for downstream filters while improving indoor air quality and reducing maintenance costs.
The Nonwoven Pocket Filter is engineered for medium-efficiency air filtration in commercial, industrial, and institutional environments.
Constructed from high-quality synthetic nonwoven filter media using advanced ultrasonic welding technology, the filter pockets maintain their shape during operation and ensure uniform airflow distribution across the entire filtration surface.
The progressive-density media structure allows particles to be captured throughout the depth of the filter, resulting in higher dust holding capacity, longer service life, and lower energy consumption.
Designed for use as a secondary filtration stage after pre-filters, pocket filters effectively remove fine dust, pollen, fibers, and airborne contaminants before air enters sensitive environments.
