Problem
The air quality
does not improve,
even though the air
purifier has been
operating for a long
time.
It takes a long time
to reach the target
humidity level.
I do not see water
vapor coming out
of the appliance. Is
it working?
The appliance
produces a strange
smell.
The appliance is
extra loud.
The appliance still
indicates that I
need to replace a
filter, but I already
did.

Possible solution
• Check if the packing material is removed from the filters.
• One of the filters has not been placed in the air purifier
or a filter is not placed properly. Make sure that all filters
are properly installed in the following order, starting with
the innermost filter: 1) NanoProtect filter Series 3 (FY1410);
2) NanoProtect filter Active Carbon (FY1413); 3) pre-filter.
• The air quality sensor is wet. Make sure that the air quality
sensor is clean and dry (see chapter "Cleaning").
• NanoCloud technology evenly distributes invisible water
vapour into your room. In dry conditions moisture from the
humidifier 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 humidification and purification performance, it's
recommended to close doors and windows during use.
• When mist is very fine, it is invisible. The appliance has a
NanoCloud humidification technology, which produces
healthy humid air from the outlet area without formation of
water mist. Therefore, you cannot see the mist.
• The first 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 filters, contact your
Philips dealer or an authorized Philips service center.
• The filter may produce smell after being used for a while
because of the absorption of indoor air. Remove the filter
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 filter.
• You have not removed all packaging material of the filters.
Make sure that you have removed all packaging material.
• Change the fan speed to lower fan speed level.
• Perhaps you did not touch and hold the Timer/Reset button
correctly. Plug in the appliance, touch
appliance, and touch and hold the Timer/Reset button
3 seconds.
