Possible solution
• Check if the packing material is removed from the filter�
• The filter has not been placed in the appliance� Make sure that
the filter (FY3430/30) 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 alcohol�
• Filter reaches the end of life� Replace the filter with a new one�
• The particle sensor is dirty� Clean the particle sensor (see the
chapter "Cleaning and maintenance")�
• 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
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�
• 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�
• Perhaps you did not reset the filter lifetime counter� Switch on
the appliance� Then touch and hold the reset button (
3 seconds�
) for
