What Does High Efficiency Gas Absorber (HEGA) Mean?
A High-Efficiency Gas Absorber (HEGA) is a carbon cloth filter with activated carbon as its main component. HEGA filters can absorb odors, gases, and volatile compounds (VOCs).
HEGA filters are also lightweight and easy to carry, making them a suitable option for respiratory PPE for the public.
To earn the HEGA designation, a filter must perform at a minimum efficiency of 99.9% when tested in accordance with the Institute of Environmental Sciences and Technologies (IEST) designation: IES-RP-CC-008-84, Recommended Practice for Gas Phase Adsorber Cell.
