Cleaning the air quality sensor
The air quality sensor lens should be cleaned every 2 to 3 months to make sure the air purifier properly
detects the particles in the air.
Using a dry cloth or a so brush, remove dust
from inside and outside the cover. Make sure
the 2 holes in the cover are free of dust.
Using a slightly damp cotton swab, clean the
air quality sensor lens, which is the circular
mirror-like surface at the upper le section
inside the cavity.
Dry the sensor lens with a dry cotton swab
and close the cover.
Open the air quality sensor cover.
Turn OFF and unplug the unit. Find the air quality sensor cover located under
the pre-filter at the back of the unit.
Clean the lens only, nothing else, and do so very delicately.
DO NOT remove the foam cover piece on the cover.
