Our HEPA 13 filter retains minute particles in the range of a few micro meters thanks to its impressive separation degree of 99.95 percent. Aerosols, viruses and germs are almost completely absorbed due to the high filter capacity and not released back into the ambient air. Certified according to test standard DIN EN 1822:2019, the HEPA 13 filter also complies with the high safety standards in hygienically sensitive areas.
