The Eurovent Association has released the fourth edition of the widely-applied Eurovent Recommendation 4/21 – Energy Efficiency Evaluation of air filters for general ventilation purposes.

The updated guidelines set out a new method for the determination of the annual energy consumption for filters operating at an airflow rate other than normal.

Eurovent 4/21 was first published in 2014 and has since gone through several revisions and editions.

The aim of this guideline is to assess the yearly energy consumpti8on based on a laboratory rest procedure which can be the basis for an energy efficiency classification, to give the user of air filters guidance for the filter selection.

The guidelines were compiled by participants of the Eurovent Product Group “Air Filters” (PG-FIL) which represents the bulk of manufacturers of these products active on the EMEA (Europe, Middle East and Africa) market.

It sets a new method for the determination of the annual energy consumption for filters operating at an airflow rate other than nominal.

The new methodology has been developed based on a series of tests carried out by the PG-FIL technical subcommittee, and unanimously approved for publication by the group at their last meeting.

Product group chair, Jan Andersson, said the new methodology paves the way for easy filter evaluation.

“It brings new opportunities when evaluating the energy efficiency of ventilation units and supports the upcoming revisions to Ecodesign requirements.”
