Hepa Filter Particle Size Chart. It is an acronym for high efficiency particulate air filter as officially defined by the u s. To put particle size into perspective a human hair ranges in size from 17 181 microns in diameter most allergy causing pollen is 10 40 microns duct particles can be as small as 2 5 10 microns bacteria are generally in the range of 0 3 5 microns and viruses the smallest particles range in size from 0 004 0 1 microns.
