MERV Rating 8-13: Fumes, Smoke, Mold, Dust Mites, Smog, etc.
Depending on the type of industry, these filters are used in both commercial and residential structures. They can filter out particles with sizes from 3.0-10.0 microns. Dust from sand and cement work is trapped in the filters, along with dust, dust mites, mold spores, and carpet fibers.
