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 cases the intervals between changes may be
shorter.
