•
Alternatively, you can clean the pre-filter by
removing the dust with a vacuum cleaner.
•
Make sure that the pre-filter is completely dry. If it
is still wet, bacteria may multiply in it and shorten

•
Make sure that the side with the two projections
is pointing towards you, and that all hooks of the
pre-filter are properly attached to the purifier.
