Changing times for the filter mat
The operating modes and the quality of the suctioned
air (e.g. dust content) has a strong influence on the filter
service life.
The filter should be checked on a weekly basis,
eventually daily basis, for dust build-up.
In these operational cases, shorter change intervals are
possible.
