Problem Possible solution
The lter turns
yellowish after some
time.
The yellow deposits is a natural eect of the wick material,
and it has no impact on humidication performance. Clean
the humidication lter frequently to remove the scale, and
replace the humidication lter every three month.
There is unpleasant
smell coming out from
the humidier.
• Make sure that the water tank is lled with water.
• Clean the humidication lter (see the chapter ‘Clean the
humidication lter’).
No air comes out of
the air outlet.
Put the plug of the humidier into the wall socket and switch
on the humidier.
I do not see visible
mist coming out of
the humidier. Is it
working?
When mist is very ne, it is invisible. This humidier has a
NanoCloud humidication technology, which produces
healthy humid air from the outlet area without formation of
water mist. Therefore, you cannot see the mist.
I want to check
whether the humidity
sensor works or not.
Gently blow moist air into the humidity sensor. After a while,
the humidity indication changes. The indication can show the
ambient humidity level from 20%RH to 95%RH.
The humidier still
works even when
environment reaches
target humidity.
The humidier will turn on at intervals, in order to ventilate air
around humidity sensor, therefore get more accurate reading
on environment humidity. This setting applies to the humidity
level setting, including the Auto mode.
