Review of Eurovent 4/23-2018 Selection of EN ISO 16890rated air filter classes for general ventilation applications

For the requirement of indoor air quality for particulate matter filtration efficiency (ePMx) testing, the International Organization for Standardization (ISO) has developed the ISO 16890:2016 series standards, in which stipulate the test methods and classification of ePMx. In recent years, the ePMx of air filters for indoor and outdoor air environment have been studied and discussed by some domestic institutes and researchers. So far these studies are difficult to apply in design and air filter selection due to uncertainties of major factors. Eurovent 4/23-2018 is a complement of ISO 16890:2016. It is more concise and practicable for the designers. Reviews some key points of Eurovent 4/23-2018, and proposes suggestions for domestic studies.
