Symptom Cause
Hissing and crackling
noises are coming out
Hissing and crackling noises are coming out
from the streamer unit. They are noises associated with discharge.
The air smells
The odour from the air outlet is concerning. In rare cases, odour from the pleated filter
may be noticed at the beginning of use.
Also, odour may come out from the air outlet
due to the small amount of ozone generated
during streamer discharge.
The filter is discoloured
The pleated filter turns yellow. The filter may discolour due to the UV beams.
The blue LED does not
turn on
The blue LED goes off during operation. The blue LED turns off when the fan is
stopped.
UV beams cannot be
confirmed
UV beams cannot be confirmed by the
naked eye.
Since deep ultraviolet rays (UVC) are not
visible, they cannot be confirmed by the
naked eye.
Low-register or buzzing
operating sound is
generated
The low-register or buzzing operating sound is
the result of mounting the UV streamer air
purifier unit.
In rare cases, mounting the unit may cause
an operating sound.

display keeps blinking
