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
