This chapter summarizes the most common problems you could encounter with the
appliance. If you 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 light has been on continuously but you
have not replaced the corresponding filter. As a result, the
appliance gets locked. In this case, replace the filter and reset
the filter lifetime counter.
The airflow that
comes out of
the air outlet
is significantly
weaker than
before.
The pre-filter is dirty. Clean the pre-filter (see the chapter
"Cleaning").
The air quality
does not
improve, even
though the
appliance has
been operating
for a long time.
• One of the filters has not been placed in the appliance. Make
sure that all filters are properly installed in the following
order, starting with the innermost filter: 1) NanoProtect HEPA
S3 filter; 2) NanoProtect AC filter; 3) pre-filter.
• 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 the 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
the chapter "Cleaning").
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, contact your Philips dealer or an
authorized Philips service center. The appliance may also
produce an unpleasant smell when one of the filters is dirty. In
this case, clean or replace the filter concerned.
English
21EN

lower fan speed level. When using the appliance in a bedroom
at night, choose the silent speed.

I need to replace
a filter,
but I already did.

the appliance. Then press and hold the power On/Off button
for 3 seconds.
