Problem
I need cleaner air
because I have an
allergy.
The appliance is
extra loud.
The appliance still
indicates that I need
to replace a filter, but
I already did.

Possible solution
You can change the air quality sensor sensitivity (see the chapter
"Use the appliance, section "Set the sensitivity of the air quality
sensor") to make the appliance clean the air even better.
• 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.
Perhaps you did not reset the filter lifetime counter. Switch on the
appliance. Then press and hold for 3 seconds.
