Problem Possible solution
The air quality
does not improve,
even though the air
purier has been
operating for a long
time.
• Check if the packing material is removed from the lters.
• One of the lters has not been placed in the air purier
or a lter is not placed properly. Make sure that all lters
are properly installed in the following order, starting with
the innermost lter: 1) NanoProtect lter Series 3 (FY1410);
2) NanoProtect lter Active Carbon (FY1413); 3) pre-lter.
• The air quality sensor is wet. Make sure that the air quality
sensor is clean and dry (see chapter "Cleaning").
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
humidier 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 humidication and purication 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 humidication 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 even if removing lters, contact your
Philips dealer or an authorized Philips service center.
• 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.
Make sure that you have removed all packaging material.
• Change the fan speed to lower fan speed level.
