Problem
Possible solution
The air quality does not
improve, even though the
purifier has been operating
for a long time.
•
One of the filters has not been placed in the purifier.
Make sure that all filters are properly installed in the fol
-
lowing order, starting with the innermost filter: HEPA filter
(4), activated carbon filter (3), multi-care filter (2) and
pre-filter (1).
•
The air quality sensor is wet. The humidity level in your
room is high and causes condensation. Make sure that
the air quality sensor is clean and dry (see ‘Clean the air
quality sensor’).
The color of the air quality
light always stays the same.
The air quality sensor is dirty. Clean the air quality sensor
(see ‘Clean the air quality sensor’).
I need cleaner air because I
have an allergy.
You can change the air quality sensor sensitivity (see 'Set
the sensitivity of the air quality sensor’) to make the purifier
clean the air even better.
The purifier is extra loud.
•
Please check if you have removed all the packaging
material from the filters.
•
If the appliance is still too loud; you can change the fan
speed to a lower fan speed level.
The purifier still indicates that
I need to replace a filter, but I
already did.
Perhaps you did not press the
button to reset the filter
lock properly. Plug in the purifier, press the
button and
press and hold the button for 3 seconds.
The buttons do not work.
Check if the child lock function is activated. If so, press and
hold the button again for 3 seconds to deactivate the
child lock function.
