HEPA Box Air Filters
Control dust and contaminants in hospitals, laboratories, and other demanding environments. These filters have a rigid frame that withstands fluctuations in airflow, such as those created by variable air volume systems. The sealing gasket is on the downstream side of the filter.
The trade size is the actual size of the filter.
UL Classified-rated filters meet flame retardance requirements.
