Meets the high safety standards in hygienically sensitive areas: Our highly effective HEPA-14 filter, certified in accordance with the test standard DIN EN 1822: 2019, impresses with a degree of separation of 99.995 percent and thus retains even the smallest particles in the range of a few micrometers. Even aerosols, viruses and germs are reliably and almost completely intercepted and not released back into the ambient air.
