Cleaning of Dust Pollution Detection Sensor (To be cleaned once every 2 months)
First of all, open the cover of the contamination
detecting sensor on the right side of the product.
Clean the air inlet, outlet, and around the dust
contamination detecting sensor with soft brush
or vacuum cleaner. ●
Cleaning of Filter Cover
Remove dust from surface with vacuum cleaner or
soft brush, etc. ●
Second of all, clean the lens, dust inlet, and the dust
outlet with wet cotton swab, and then remove water
with dry one. ●
In case of severe pollution, wash filter cover with clean
water and completely dry it before use.
Always make sure to unplug power cord prior to filter cleaning.
If it is not cleaned periodically, it can be a major cause
of the performance deterioration of the dust contamination
detecting sensor.
The cleaning period is subjective to the air cleaner using
environment, thus, clean it more frequently if the cleaner
is used in a dusty area.
