Scheme & grant New regulations MVHR filters: ISO16890

Filter class G4, M6, F9, and so on. For those who have a MVHR system, these terms are probably not unfamiliar. Since August 2018, something has changed: the filter standard EN779 has been replaced by ISO16890. This means that previously mentioned terms will give way to new, more specific designations. In this blog, we would like to explain the differences.
