Update with the news ISO 16990 filter standards (Coarse and Fine Filter)

The ISO 16890 test standard has been valid for the classification of air filters since January 2017 and, since August, also as DIN EN ISO 16890:2017. Since July 2018, it has completely replaced the previous industry standard EN 779. The advantage of ISO 16890 is that 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 your individual requirements much easier.
