3. If there is a slight amount of dirt, clean the filter mat at a suitable location. Depending on the
degree of pollution, you can also clean the filter mats using a vacuum cleaner. If the filter mat
is damaged, or the frequency of alarms increases, dispose of the dirty filter mat in the correct
fashion. Use a new filter mat.

a clean mat in the same direction as it was installed before the cleaning.
