HEPA filter definition

HEPA filter means a high efficiency particulate absolute air filter capable of trapping and retaining 99.97 percent of fibers greater than 0.3 micrometers in mass median aerodynamic diameter equivalent.
HEPA filter means a high efficiency particulate aerosol filter that is at least 99.97 per cent efficient in collecting a 0.3 micrometre aerosol;
HEPA filter means high-efficiency particulate air filters that are rated to achieve a minimum initial particle-removal efficiency of 99,97 % using ASTM F 1471–93;

Examples of HEPA filter in a sentence

  • A vacuum cleaner with a high-efficiency particulate air (HEPA) filter can be used to help remove nonvisible mold products from porous items such as fibers in sofas, chairs, drapes, and carpets provided the fibers are completely dry.
