HEPA is an acronym for “High Efficiency Particulate Air”. This acronym refers to a filter that is manufactured, tested, certified, and labeled in accordance with current HEPA filter standards. HEPA Filters can remove at least 99.97% of dust, pollen, mold, bacteria and any other airborne particles as small as 0.3 microns in diameter. Filter efficiency studies have shown that 0.3-microns is very close to what is known as the “Most Penetrating Particle Size (MPPS)” for HEPA filter media.

The ultra-fine, glass-fiber medium captures microscopic particles that can easily pass through other filters by a combination of diffusion, interception and inertial impaction.
