A filter designed to remove 99.97% of particulates which are 0.3 microns in diameter. HEPA filters are often referred to as absolute filters and are used to remove toxic respirable sized particles from contaminated air.
Throwaway extended pleated medium dry-type filter with 1) a rigid casing enclosing the full depth of the pleats, 2) a minimum particle removal efficiency of 99.97 percent for thermally generated monodisperse di-octyl phlalate smoke particles with a diameter of 0.3 micrometer, and 3) a maximum pressure drop of 1.0 inch w.g. when clean and operated at its rated airflow capacity.
A filter designed to remove 99.97% of a specified type of particulate material from the air.
A filter with an efficiency of at least 99.95 percent used to remove particles from air exhaust streams prior to releasing to the atmosphere.
A filter that can remove very small lead particles and prevent them from being redistributed into the air. HEPA filters are used on respirators and vacuum cleaners to prevent lead exposure from projects that disturb lead-based paint.
