HEPA 13 stands for High Efficiency Particulate Air.
Eliminates at least 99.97% of dust, pollen, mold, bacteria and any airborne particles with a size of 0.3 microns.
H13-H14 HEPA are within the highest tier of HEPA air filtration and are considered medical-grade. “A HEPA grade of H13 can remove 99.95% of all particles in the air measuring 0.2 microns in diameter, while a HEPA grade H14 removes 99.995%,” says Nagl.
According to a study by the Goethe University in Frankfurt a.M - mobile air purifiers with HEPA air filters can help to reduce the virus concentration by 90 percent within half an hour. If there is a super‐spreader in the room, mobile air purifiers reduce the risk of infection, according to the scientists at the Goethe University. To this end, the following requirements must be met by mobile room air conditioning systems:
