Problem Possible solution
It takes a long time
to reach the target
humidity level.
• NanoCloud technology evenly distributes invisible water
vapour into your room. In dry conditions moisture from the
humidier will be absorbed by walls, furniture, and other
items in your room. Ventilation of dry outside air will also
increase the time it takes to reach the target humidity.
To optimize humidication and purication performance, it's
recommended to close doors and windows during use.
I do not see water
vapor coming out
of the appliance. Is
it working?
• When mist is very ne, it is invisible. The appliance has a
NanoCloud humidication technology, which produces
healthy humid air from the outlet area without formation of
water mist. Therefore, you cannot see the mist.
The appliance
produces a strange
smell.
• The rst few times you use the appliance, it may produce
a plastic smell. This is normal. However, if the appliance
produces a burnt smell, contact your Philips dealer or an
authorized Philips service centre.
• The lter may produce smell after being used for a while
because of the absorption of indoor air. Remove the lter
and place it where it has direct sunlight and ventilation for
several hours. Re-install and try using it again. If the odor
remains, please replace the lter.
The appliance is
extra loud.
• You have not removed all packaging material of the lters.

The appliance still
indicates that I
need to replace a
lter, but I already
did.
