Tip: Alternatively, you can wash the pre-lter under a running tap. If the
pre-lter is very dirty, use a soft brush to brush away the dust. In this case,
make sure that the pre-lter is completely dry before putting it back into the
air purier. If it is still wet, bacteria may multiply in it and shorten the lifetime
of the pre-lter.

Air quality sensor
Clean the air quality sensor every 2 months for optimal functioning of
the appliance. Clean it more frequently if you use the appliance in a dusty
environment.
Note: When the humidity level in the room is very high, it is possible that
condensation develops on the air quality sensor. As a result, the AIR QUALITY
light on the control panel and the air quality light ring may indicate that the air
quality is bad even though the air quality is good. In this case you have to clean
the air quality sensor or use one of the manual speed settings.
