HEPA is a type of pleated mechanical air filter. It is an acronym for high efficiency particulate air 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.
The EN779:2012 introduces an air filter classification for fine filters F7 to F9 based on Minimum Efficiency ME. ME is defined as the lowest value of three different tests for 0.4 µm particles initial efficiency, efficiency throughout the tests loading procedure and discharged efficiency. Those air filters that do not meet the ME requirements will lose their original efficiency

The EN 779:2012 version valid from April 2012 until mid 2018 included the introduction of minimum efficiency levels for classes F7 to F9, and the renaming of classes F5 and F6 to M5 and M6. By mid 2018, EN 779 willpletely replaced by the ISO 16890 standard
HEPA stands for High Efficiency Particulate Air. It is a standard defined and developed by the U.S. Department of Energy during the 1940s as part of their efforts to contain the spread of particles and contamination resulting from nuclear testing. This standard has since moved into the consumer market and hasmonplace for air purifiers.
