European filter classification

How can one establish, as the end-user, whether a flter will provide the envisaged air quality? Throughout Europe, air filters are classified according to two standards: ISO 16890  for course and fine filters, and EN1822:2009 for HEPA and ULPA filters. Filters that are tested for compliance with these standards naturally meet stringent requirements. During such tests, the filters are exposed to circumstances that indicate precisely how they will perform in practice. As the customer, it is a comforting thought to know that all the products AFPRO Filters supplies are compliant with European classification. The filters are tested in both our own and independent laboratories. Furthermore, AFPRO Filters complies with the stringent requirements of the Eurovent certification program. This guarantees that the actual filter performance is in line with the specifications presented.

This is why air filters are classified according to several standards:

  • ISO 16890* (formally EN779:2012 for the EU and ASHRAE 52.2 for the USA) for coarse and fine filters.
  • EN1822:2019 for absolute filters.

MPPS

The MPPS efficiency is leading in these tests. MPPS stands for most penetrating particle size. This refers to the dimensions of those particles that are the most difficult to trap. It generally lies in the region of 0.1to 0.2 microns (μm). The MPPS has to be established before subjecting a filter to tests.
The table contains detailed information on the European filter classifications. AFPRO Filters supplies test certificates with all HEPA and ULPA filters. You can rest assured that the filter supplied is of suitable quality. However, we do recommend subsequent validation of the filters following installation, to ensure that they were not damaged during transport or fitting.
