Cleaning The Air Quality Sensor; Cleaning The Pre-Filter - Philips AC3259 User Manual

Cleaning the air quality
sensor
Clean the air quality sensor every
2 months for optimal functioning of the
purifier. Clean them more frequently
if you use the purifier in a dusty
environment.
Note
• When the humidity level in the
room is very high, it is possible that
condensation develops on the air
quality sensor. As a result, the air
quality light may indicate that the air
quality is bad even though it is good.
In this case you have to clean the
air quality sensor or use one of the
manual speed settings.
1
Clean the air quality sensor inlet
and outlet with a soft brush (fig.w).
2
Open the air quality sensor cover
(fig.x).
3
Clean the air quality sensor, the
dust inlet and the dust outlet with
a lightly moistened cotton swab
(fig.y).
4
Dry them with a dry cotton swab.
5
Reattach the air quality sensor
cover (fig.z).
