are unable to solve the problem with the information below, contact the Consumer Care Center in your
country.
Problem
Possible solution
The appliance does not
work even though it is
plugged in.
•
The filter replacement alert has been on continuously but you have
not replaced the corresponding filter. As a result, the appliance is now
locked. In this case, replace the filter and long press to reset the filter
lifetime counter.
The airflow that comes
out of the air outlet is
significantly weaker
than before.
•
The surface of the filter is dirty. Clean the surface of the filter (see the
chapter “Cleaning and maintenance”).
The air quality does not
improve, even though
the appliance has been
operating for a long
time�
•
Check if the packing material is removed from the filter.
•
The filter has not been placed in the appliance. Make sure that the filter
(FY4440/30) is properly installed.
•
The particle sensor is wet. The humidity level in your room is high and
causes condensation. Make sure that the particle sensor is clean and dry
(see the chapter “Cleaning and maintenance”).
•
Room size is large or the outdoor air quality is poor. For optimum
purification performance, please close the doors and windows when
operating the air purifier.
•
There are indoor pollution resources. For instances, smoking, cooking,
incense, perfume or alchohol.
•
Filter reaches the end of life. Replace the filter with a new one.

quality light always
stays the same.
•
The particle sensor is dirty. Clean the particle sensor (see the chapter
“Cleaning and maintenance”).
The appliance produces
a strange smell.
•
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 filter, 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 gases. It’s recommended that you
reactivate the filter by putting it in direct sunlight for repeated use. If
odor still exists, replace the filter.
The appliance is extra
loud.
•
It's normal if the appliance runs at the Turbo mode.
•
In the Auto mode, if the appliance is too loud, maybe the appliance runs
at high speed because air quality becomes worse, or your personalized
setting in App triggers a higher fan speed. You can choose the Sleep
mode, or change the settings in the App.
•
If there is abnormal sound, contact the Consumer Care Center in your
country.
•
If anything drops into air outlet, it may also cause abnormal loud sound.
Immediate turn off appliance, turn appliance upside down, to get foreign
objectives out of appliance.

that the back cover is
opened.
•
Shut off the power first, then install the back cover correctly. Connect the
appliance with power and retry.
