from air outlet.
Request follow-up service.
Replace filters with new ones and
clean up pre filter.
Install it on flat surface.
Is designated replacement period of
Integrated-type filter over?
Decreased
deodorization.
Replace filters with new one.

“Low” or “standard”.
Does the lamp keep lighting blue
(Pollution level is low)?
Set the level of detection sensitivity
“High” or “standard”.
Make sure unit is properly
plugged in.
Request follow-up
service.
Is there any dust stuck onto lens
of particle sensor?
Clean up lens of particle sensor.
