Product Description

High-efficiency particulate air (HEPA) , also known as high-efficiency particulate absorbing and high-efficiency particulate arrestance. is an efficiency standard of air filter. Filters meeting the HEPA standard must satisfy certain levels of efficiency. Common standards  require that a HEPA air filter must remove-from the air that passes through-at least 99. 95% ( European Standard) [4] or 99.97%  (ASME, U.S. DOE) [5] [6] of particles whose diameter is equal to 0.3 μm; with the filtration efficiency increasing for particle diameters  both less than and greater than 0.3 μm. [7] See the Mechanism and Specifications sections for more information.
