High Efficiency Particulate Air (H.E.P.A.) or "absolute" filters are used where critical environments such as hospitals, labs, clean rooms and biohazard sites require absolute protection from contamination. Efficiencies are usually in the 99.97% range on particles as small as
0.3 micrometres (microns).
