Respiratory protection is about safety through filtered air without pollutants. As filtration experts, we are aware of this great responsibility and are committed to taking it on. After all, filtration has been firmly anchored in our DNA for over 60 years.

Since the beginning of the coronavirus pandemic, we have used our expertise in filtration to fight the virus. Thanks to high-quality filter materials, our masks offer a high level of protection against infection by aerosols and the transmission of infectious germs to other people.

In accordance with applicable standards such as DIN14683 or EN149:2001+A1:2009, the various respiratory masks have been subjected to various performance requirements to ensure a high standard of quality. For example, the filter effectiveness for bacteria (BFE), the pressure difference for measuring breathing resistance, biological safety and microbiological purity were tested.
