According to European standards, there are 17 classes of filters the higher the class, the greater the efficiency. Classes E10 to E12 are Efficient Particulate Air EPA filters, H13 and H14 are HEPA filters, and U15 to U17 are Ultra Lowration Air ULPA filters.
Prefilter captures large dirt and dust particles. HEPA filter captures nearly all remaining particles and germs. Healthy Climate HighEfficiency Particulate Air HEPA Filtration System. 5 / 5. June 16, 2020. We installed 3 hepa filter in may of 2016. Have 7 cats on level and 6 on another level . Plus wool rugs though out the home.
Highefficiency particulate air HEPA, also known as highefficiency particulate absorbing and highefficiency 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 removefrom the air that passes throughat least 99.95 European Standard or 99.97
HEPA is an acronym that stands for High Efficiency Particulate Air. This is a pleated filter that traps airborne particles as they pass through an air purifier. A true HEPA filter removes 99.97 of all particles that are 0.3 microns in size or larger. This is known as the HEPA standard.
HEPA highefficiency particulate air filters trap the tiniest of airborne particles down to a size of 0.3 microns. This is far too small to be seen by the naked eye. As such, true HEPA filters those that have passed rigorous testing remain the gold standard of filtration.

Also known as smallparticle filters, these HEPA filters can capture more than 99.97 percent of particles that are at least 0.3 microns in size and prevent them from being returned into the air
Higher Efficiency. 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.
What is a HEPA filter? HEPA is a type of pleated mechanical air filter. It is an acronym for "high efficiency particulate air filter" as officially defined by the U.S. Dept. of Energy. 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.
By definition, a High Efficiency Particulate Air HEPA filter is at least 99.97 efficient at capturing particles 0.3 µm in size. This 0.3 µm particle approximates the mostrating particle size MPPS through the filter. HEPA filters are even more efficient at capturing particles larger and smaller than the MPPS. Thus, HEPA filters are
