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.
