Problem Possible solution
The lter discolors
after some time.
• The deposit 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 6 months.
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 power 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. When the desired
humidity level is reached, the color of the humidity
indicator light is blue. When the humidity level is not
reached, the humidity indicator light is red.
If the humidier is not
used for a long time,
How to store and
reuse it?
When the humidier is not used for a long time, bacteria and
mold may grow on the lters. please follow below steps for
storage and reuse.
• Clean the water tank thoroughly and dry the humidication
lter before storage.
• Check the lters before you start using the humidier
again. If the lter is very dirty with dark spots, replace it
(Please refer to the chapter “Replacing the humidication
