EVIA guidance on filter quality


Filters are an essential element in ventilation systems in ensuring good Indoor Air Quality (IAQ) and levels of hygiene. With the introduction of the new ISO 16890 (2016-12) the filter testing and qualification procedure has been changed to a more realistic classification based on ePM 1, ePM2.5, and ePM10 values. This allows a detailed filter selection based on outdoor particulate matter. Therefore, the new standard is an important improvement. EVIA has produced some further guidance for supplementary explanation.
