EN779:2012
All our air filters in the range of G2 - F9 are tested according to the current standard EN779:2012. We cooperate with several independent European testing laboratories to guarantee the delivery of the highest quality air filters.
Since September 2012, a few changes were introduced to the European standard EN779:2002.
The two most important changes are:
- F5 and F6 become M5 and M6. The M stands for Medium Efficiency Filter. The filtration efficiency of these filters does not change. M5 filters have an average efficiency of > 40% ≤ Em < 60% and M6 filters of 60% ≤ Em < 80%
- For air filters of classifications F7, F8 and F9 (fine filters), the new standard stipulates a minimum efficiency (ME) of F7 > 35% / F8 > 55% / F9 > 70% for 0,4 µ particles.

Testing laboratories
Our air filters are tested in renowned independent European laboratories, for example Fiatec in Germany and VTT in Finland.
