Cleaning The Air Quality Sensor - Philips AC2889 User Manual

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
Open 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).

cotton swab.
