What is a HEPA filter?

HEPA is a type of pleated mechanical air filter. It is an acronym for "high efficiency particulate air [filter]" (as officially defined by the U.S. Dept. of Energy).  This type of air filter can theoretically remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns (µm). The diameter specification of 0.3 microns responds to the worst case; the most penetrating particle size (MPPS). Particles that are larger or smaller are trapped with even higher efficiency. Using the worst case particle size results in the worst case efficiency rating (i.e. 99.97% or better for all particle sizes).

All air cleaners require periodic cleaning and filter replacement to function properly.  Follow manufacturer's recommendations on maintenance and replacement.

Minimum Efficiency Reporting Values, or MERVs, report a filter's ability to capture larger particles between 0.3 and 10 microns (µm). 

This value is helpful in comparing the performance of different filters

The rating is derived from a test method developed by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) [see www.ashrae.org ].

The higher the MERV rating the better the filter is at trapping specific types of particles.

How HEPA works in RedKey F10?

After the dust have goes into the vacuum, the pollution air will goes into the vacuum also,  some of the vacuum that’s haven’t use hepa will cause 2nd pollution in the air. As RedKey F10, we used 3 layers of HEPA vacuum for filter the dirt air , that’s wont be cause 2nd pollution in the air.
