5 Cleaning
Note
• Always turn the air purifier off and
unplug from the electrical outlet
before cleaning.
• Never immerse the air purifier in water
or any other liquid.
• Never use abrasive, aggressive, or
flammable cleaning agents such as
bleach or alcohol to clean any part of
the air purifier.
• Only the pre-filter is washable.
The HEPA and AC air filters are not
washable.
• Do not attempt to clean the filters or
air quality sensor with a vacuum.
Cleaning the body of the
air purier
Regularly clean the inside and outside
of the air purifier to prevent dust from
collecting.
1 Use a soft, dry cloth to clean both
the interior and exterior of the air
purifier.
2 The air outlet can also be cleaned
with a dry, soft cloth.
Cleaning the air quality
sensor
Clean the air quality sensor every
2 months for optimal functioning of the
purifier.
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.
1 Switch off the air purifier and
unplug from the wall outlet.
2 Clean the air quality sensor inlet
and outlet with a soft brush (fig.u).
3 Remove the air quality sensor cover
(fig.v).
4 Clean the air quality sensor, the
dust inlet and the dust outlet with a
damp cotton swab (fig.w).
5 Dry all parts thoroughly with a dry
cotton swab.
6 Reattach the air quality sensor
cover (fig.x).
