Problem Possible solution
The airow that
comes out of
the air outlet is
signicantly weaker
than before.
• The pre-lter is dirty. Clean the pre-lter (see chapter
"Cleaning").
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 lters.
• One of the lters has not been placed in the appliance.
Make sure that all lters are properly installed in the
following order, starting with the innermost lter:
1) NanoProtect lter HEPA Series 3; 2) NanoProtect lter
Active Carbon; 3) pre-lter.
• The air quality sensor is wet. The humidity level in your
room is high and causes condensation. Make sure that the
air quality sensor is clean and dry (see chapter "Cleaning").
The color of the air
quality light always
stays the same.
• The air quality sensor is dirty. Clean the air quality sensor
(see chapter "Cleaning").
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 appliance may also produce an unpleasant smell
when the lter is dirty. In this case, clean or replace the
lter concerned.
The appliance is
extra loud.
• If the appliance is too loud, you can change the fan speed
to a lower fan speed level. When using the appliance in a
bedroom at night, choose the sleep mode.
The appliance still
indicates that I
need to replace a
lter, but I already
did.
• Perhaps you did not reset the lter lifetime counter. Plug
in the appliance, touch
to switch on the appliance, and
touch and hold the reset button
for 3 seconds.
Error codes "E1",
"E2", "E3" or "E4"
displays on the
screen.
• The appliance has malfunctions. Contact the Consumer
Care Center in your country.
