HEPA filter out 99.97% of airborne contaminants that are larger than 0.3 microns.

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.
 
These filters are a necessity for any clean laboratory workspace.
