Brussels, Belgium, 9 October 2018: The Eurovent Product Group ‘Air Filters’ has published an updated version of its Recommendation 4/23, ‘Selection of EN ISO 16890 rated air filter classes for general ventilation applications’, the organisation announced in a Press communiqué. The 2018 version is aligned with European standardisation developments, the communiqué said.

According to Eurovent, the updated version includes a hands-on table, which shows that required filtration efficiencies can be reached by using different filters or different combinations of filters. The communiqué said that most national member associations of Eurovent are working on translating the updated version into other languages. The communiqué further said that a Brazilian market version is under development, following multiple requests.
