High Efficiency Particulate Air Filter Is Made Of

This type of air filter can theoretically remove at least 99 97 of dust pollen mold bacteria and any airborne particles with a size of 0 3 microns µm.

High efficiency particulate air filter is made of. Most modern cell processing facilities have ventilation systems with filtered air using high efficiency particulate air hepa filters a technology developed in the 1940s. High efficiency particulate air hepa also known as high efficiency particulate absorbing and high efficiency particulate arrestance is an efficiency standard of air filter. It is an acronym for high efficiency particulate air filter as officially defined by the u s. Though the hepa standard and certification process wasn t established until 1983 development of hepa filters dates back to world war ii when american scientists with the.

What sets hepa filters apart from the rest is their claims are more than just claims. Filters meeting the hepa standard must satisfy certain levels of efficiency. Hepa is an acronym that stands for high efficiency particulate air so a hepa filter is a high efficiency particulate air filter. Hepa which stands for high efficiency particulate air is a designation used to describe filters that are able to trap 99 97 percent of particles that are 0 3 microns.

Common standards require that a hepa air filter must remove from the air that passes through at least 99 95 european standard or 99 97. Hepa is a type of pleated mechanical air filter. High efficiency particulate air hepa filters must meet the efficiency rating of 99 97 on particles as small as 0 3 microns set by the us department of energy in order to be a true hepa filter 5 some hepa filters marketed for consumers do not meet these standards and are not true hepa filters with the same capability or efficiency.
