• 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 particle sensor and the air quality light may indicate a
poorer air quality even though the air quality is good.If this occurs,
clean the particle sensor.
Clean the particle sensor every month for optimal functioning of the
appliance.
