ISO 16890 - the new filter test standard
The new testing standard ISO 16890 for filter testing and classification has been valid since December 2016. The ISO 16890 will replace the EN779 in the medium term. A major innovation is that the filter efficiency levels are determined in relation to the particulate matter classes PM1, PM2,5 and PM10 used by WHO or environmental authorities.
