Box Filters

Auth-HEPA

Auth-HEPA Standard Box Series are box-style HEPA air filters designed for built-up filter banks, side-access housings, and equipment requiring rectangular filter configurations.

Each filter is individually tested and available in efficiencies from 99.97% to 99.9995% at 0.3 μm. The Standard Box design offers reliable high-efficiency particulate removal in a compact format, distinguishing it from V-bank filters that provide expanded media area for lower pressure drop and higher airflow.
