Possible solution
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 pre-filter is dirty. Clean the pre-filter (see the chapter "Cleaning").
• 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 filter HEPA Series 3; 2) NanoProtect
filter AC; 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 air quality sensor is dirty. Clean the air quality sensor (see the chapter
"Cleaning").
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.
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
silent speed.
