New air filter classification

By July 2018, the ISO 16890 completely replaced the industry standard EN 779. The advantage: Filter efficiency is determined realistically using the four dust categories PM1, PM2,5, PM10 and coarse dust. This makes the selection of the best possible filters for individual requirements much easier.
