GUIDELINES

T
he 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 nominal.
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 consumption based
on a laboratory test procedure which can be the basis for an
energy efficiency classification, to give the user of air filters
guidance for the filter selection. This document was prepared
in a joint effort by participants of the Eurovent Product Group
‘Air Filters’ (PG-FIL), which represents a vast majority of all
manufacturers of these products active on the EMEA market.
The fourth edition of this well-established Industry
Recommendation includes a new Annex 1, which sets out 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 and
analyses carried out by the PG-FIL Technical Subcommittee, and
unanimously approved for publication by the group during their
last meeting in Turin.
Jan Andersson (Camfil), chairman of the Product Group
‘Air Filters’ and its Technical Subcommittee, states, “This new
methodology paves the way for easy filter evaluation not
only under the reference test conditions but also at the actual
operating point. It brings new opportunities for evaluation

of the energy efficiency of ventilation units, also in the light
of the upcoming requirements of the revised Commission
Regulation (EU) No 1253/2014 (Ecodesign requirements for
ventilation units).”

is available free of charge. For non-members, a fee of EUR69
(R1120) is applied. It should be noted that the Eurovent
Association does not grant any certification based on this
document. Certification is the subject of Eurovent’s sub-unit
Eurovent Certita Certification, which runs independently from the
association framework. RACA
