Eurovent publishes updated Recommendation 4/23

17 January 2022

1 min read

Brussels, 18 January 2022. The Eurovent Product Group ‘Air Filters’ has published an updated version of the Recommendation 4/23 ‘Selection of EN ISO 16890 rated air filter classes for general ventilation applications.’ It aligns with the 2021 WHO global air quality guidelines.

Based on the latest evidence on the health effects of exposure to airborne pollutants, the World Health Organization (WHO) has significantly reduced the recommended levels of PM2,5 and PM10 concentrations. Dr. Marc Schmidt, Chairman of PG-FIL stated: “The current update of the widely recognised Eurovent 4/23 aims to align guidelines for ISO 16980 rated filter selection with the latest WHO recommendations in order to increase the level of human health protection.”

The Recommendation includes a comprehensive set of guidelines on the selection of air filters for general ventilation applications, which makes full use of potential EN ISO 16890 offers in terms of Indoor Air Quality. The document, which was jointly developed by the participants of the Eurovent Product Group ‘Air Filters’ (PG-FIL), is based on a deep technical understanding of filtration and the experience of global air filter manufacturers. It is addressed to all HVAC professionals dealing with ventilation systems, particularly designers, facility managers and manufacturers of equipment incorporating air filters.

The document can be downloaded free of charge in the Eurovent Document Library. A printed version can be requested by all filter manufacturers that are members of Eurovent.
