Capacity calculation for air cleaners

Instructions for use:

You can use the following method to quickly and easily determine the air cleansing performance required for your rooms. This capacity calculation for air cleansers should be seen as a rough guide - it is not a substitute for a proper calculation in accordance with existing norms. Please do not hesitate to contact us if you have any questions.

The following items must be included in order to be able to determine the required air cleansing performance:

  1. What is the volume of the room in cubic metres?
  2. Which pollutants are to be filtered?
  3. What kind of room is available?
  4. Alternatively, the desired number of air change rates may be specified directly.

Room volume calculating

Filtering of pollutants (selection of filters)

coarse dust filter (G4)

heavy industry dust, fine sand, raindrops, coarse dust

fine dust filter (F7) incl. coarse dust filter

hair, pollen, fungus spores, plant spores

filter for suspended matter (H13) incl. fine dust filter incl. coarse dust filter

house dust mite allergens, cement dust, mould, mould spores, mineral fibre dusts, flue ash, coal dust, insecticides, fog (atmospheric), descending fine dust, pollen pieces, diesel soot, germs, anthrax spores, bacteria, paint pigments, cat allergens, oil mist, soot, tobacco smoke, asbestos dust, smog, viruses.

Results of the calculations [m³/h]:


The results from these calculations state performance requirements which the appliances have to meet with regard to the selected filter chain, room volume and the number of air exchange rates. TKL air cleansing systems cover the performance spectrum from 380m³/h to 4.200m³/h. If higher performances are required, then a combination of appliances must be selected.
