Cleaning the air quality
sensor
Clean the air quality sensor every
two months for optimal functioning
of the appliance. Clean it more
frequently if you use the appliance
in a dusty environment.
Note
• If the air purifier is used in a
dusty environment, it may need
to be cleaned more often.
• If the humidity level in the room
is very high, condensation may
develop on the air quality sensor
and the air quality light may
indicate a more poor air quality
even though the air quality is
actually good. If this occurs,
clean the air quality sensor or
use the air purifier on a manual
speed setting.
