Product Details

What does the term HEPA mean? HEPA is an acronym for “High Efficiency Particulate Air” that refers to a filter that is manufactured, tested, certified, and labeled in accordance with current HEPA filter standards. There are several sub-classes within the HEPA classification. The minimum HEPA category requires the filter to capture 99.97% of the 0.3-micron (0.000012-inch) particles in the air passing through the filter.

What makes a HEPA filter so efficient? 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. To meet the minimum requirements of a HEPA filter, the filter must be tested and certified to prove that it will remove at least 99.97% (9,997 out of 10,000) of particles 0.3-micron in diameter from the air passing through the filter. Particles that size are about 300 times smaller than the diameter of a human hair, and 25 to 50 times smaller than we can see. To a HEPA filter, catching a one-micron particle (1/1,000,000 of a meter) is the equivalent of stopping a cotton ball with a door screen.
