Problem
The color of the air
quality light always stays
the same.
I do not see water
vapor coming out
of the appliance. Is it
working?
The appliance
produces a strange
smell.
I need cleaner air
because I have an
allergy.
The appliance is extra
loud.
The appliance still
indicates that I need
to replace a filter, but I
already did.
Possible solution
• The air quality sensor is dirty. Clean the air quality sensor (see the
chapter "Clean the air quality sensor").
• There is not enough ventilation in the room. Open a window, to improve
the air circulation.
When water vapor is very fine, it is invisible. With the NanoCloud
humidification technology, the appliance produces healthy humid air from
the outlet area without formation of water mist.
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 centre. The appliance
may also produce an unpleasant smell when one of the filters is dirty. In
this case, clean or replace the filter concerned.
You can change the air quality sensor sensitivity (see the chapter "Use the
appliance, section "Set the sensitivity of the air quality sensor") to make the
appliance clean the air even better.
• Please check if you have removed all the packaging material from the
filters.
• If the appliance is still too loud, you can change the fan speed to a lower
fan speed level.
