Eurovent publishes ISO 16890 air filter update

Following its meeting during the Eurovent Summit in Seville, the Eurovent product group ‘Air Filters’ has published an updated version of its popular Recommendation 4/23 – Selection of EN ISO 16890 rated air filter classes for general ventilation applications.

The 2018 version is aligned with European standardisation developments. It includes a hands-on table, which shows that required filtration efficiencies can be reached by using different filters or different combinations of filters.

Eurovent Recommendation 4/23 (2018) constitutes a comprehensive guideline, which supports a swift transition away from EN 779 while making full use of the potential EN ISO 16890 offers in terms of indoor air quality.

Jointly developed by participants in the product group ‘Air Filters’ (PG-FIL), the publication is addressed to all HVAC professionals dealing with ventilation systems, particularly design consultants, facility managers and manufacturers of equipment incorporating air filters. 

The document can be downloaded free-of-charge within the document webshop of Although a standard by nature, the document has been published in a guidebook style, allowing engineers on the road to easily carry it with them. A printed version can be requested at all filter manufacturers that are members of the Eurovent Association.

The Recommendation will be regularly updated as new testing data becomes available.
