Cleaning The Air Quality Sensor; Cleaning The Pre-Filter - Philips AC5659 Mode D'emploi

Cleaning the air quality
sensor

2 months for optimal functioning of the
purifier.
Note

environment, it may need to be
cleaned more often.

very high, condensation may develop
on the air quality sensor and the air
quality light may indicate a poorer air

actually good. If this occurs, clean the
air quality sensor or use the air purifier
on a manual speed setting.
