Different filter classes

Filters are one of the most important parts of your ventilation system. Without a good filter, your ventilation system will not work optimally. Filters determine the air purification process and filter particles and dust particles from the air. This way the fan can work optimally. It is important to select the right filtering, you do this based on the model and the available space.

There is an important difference between the different filter classes. The standard G3 or G4 filters stop particles that you can still see with the naked eye. The finer structure of F7 filters stops, among other things, pollen and fine dust. These are so small that they are not visible to us.

New Filmetorm

Fresh and especially pure air in your home is the central starting point. The increasing particulate matter and the resulting allergies are, in addition to energy-efficient building, central to the development of our solutions for a healthy indoor climate. Since July 1, 2018, the new Filternorm ISO 16890 has started in Europe. Because particulate matter has different dimensions and shapes, the standard was now also being adjusted with which the efficiency of the filters is tested. The new standard now splits filters into four groups that filter different dust particles:

  • ISO Coarse: such as sand or hair
  • EPM 10: Like pollen
  • EPM 2.5: such as substance EPM 1: such as combustion particles
In order to be placed in a category, the filter must stop at least 50% of the relevant particles. This new classification gives an accurate indication of which particle sizes are filtered from the air. In concrete terms, this means that the name of the filters will change to:
  • Filter F7 becomes ISO EPM1
  • Filter G4 becomes ISO Coarse
  • Filters can stop the smallest particles. (ISO EPM1)
