Introduction
Congratulations on your purchase and welcome to Philips!To fully benefit
from the support that Philips offers, register your product at www.philips.
com/welcome.
With this new CleanAir System you breathe cleaner air. For the best results,
place the CleanAir System in a room where you spend most of your time,
e.g. the living room or bedroom.
Wherever there are people, plants or pets, there are airborne particles that
can affect your well-being, especially if you suffer from allergies. Because of
these particles, the air inside a room may be more polluted than the air in
a large city.
Normally, particles are invisible and odourless. Nevertheless they can affect
your health.The CleanAir System reduces the amount of animal dander
and industrial pollutants in the air, and therefore improves the air quality.
It also filters out ultrafine particles larger than 20 nanometres, including
bacteria and some viruses. According to publications of the World Health
Organization, the avian and human influenza viruses and the Legionella
bacterium are larger than 20 nanometres.
Filtration in several stages
The air cleaner has a unique multi-stage filtration system that guarantees
the best air quality:
-
- Stage 1:The pre-filter has been treated with antibacterial substances. It
catches big particles like human hair, pet hair etc.
-
- Stage 2:The formaldehyde filter (supplied with AC4074) removes
formaldehyde and other volatile organic compounds (VOCs). In
combination with the HEPA filter, the multi-care filter filters out dust,
pollen and ultrafine particles larger than 20 nanometres, including
bacteria and some viruses.According to publications of the World
Health Organization, the avian and human influenza viruses and
Legionella bacterium are larger than 20 nanometres.
Note:The AC4074 and AC4072 are suitable for both the formaldehyde filter
and the multi-care filter. When you replace the filter present in your type, you
can choose the filter (formaldehyde or multi-care) that suits your needs best.
-
- Stage 3:The activated carbon filter removes odours and harmful gases
effectively.
-
- Stage 4:The high-performance composite HEPA filter with anti-
bacterial coating effectively removes fine dust and cigarette smoke,
while the antibacterial and anti-mould functions of organic antibacterial
materials eliminate germs and mould.

Filter replacement
Filter maintenance
This air cleaner is equipped with the HealthyAirProtect Lock feature to
ensure that the filters are in optimal condition when the appliance is
operating.When one of the filters is almost full and has to be cleaned or
replaced, the appropriate filter replacement light starts to flash.When you
do not replace filter 2, filter 3 and/or filter 4, the appliance stops operating
and the appliance is locked.
When the appliance is locked, the filter replacement light of the filter
concerned lights up on continuously.
Note: Only replace a filter when the corresponding filter replacement
light flashes. If you replace the filter before the filter replacement light starts
flashing, the lifetime counter will not be reset but will continue counting the
lifetime of the previous filter.As a result, the filter replacement light will start
flashing much too soon.
Filter replacement lights
The filter replacement lights indicate which filter has to be cleaned or
replaced.

Troubleshooting
This chapter summarises 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 Centre in your country.
Problem Possible solution
The appliance doesn’t
work.
You ignored the filter replacement alerts.You did not replace the filter
when the filter replacement light started flashing and did not respond when
the appliance started to beep every 30 minutes after approx. 2 weeks.As
a result, the appliance is now locked and you have to replace the filter and
reset the appliance (see chapter ‘Filter replacement’) so that the appliance
can operate again.
No air comes out of the
air outlet
The appliance is not switched on. Put the plug in the wall socket and switch
on the appliance.
The air quality is good and the auto mode is activated. In this case, the
appliance switches off automatically when the air is clean to save electricity.
The fan speed does not
change when the auto
mode is activated.
When the room becomes dark, the night mode is activated automatically
when the appliance is in auto mode. In this case, the fan speed is set to a
very low level. If you want to change the fan speed, press the fan speed
button one or more times to set the desired fan speed.
The airflow that comes
out of the air outlet is
significantly weaker than
before.
The pre-filter is dirty. Clean the pre-filter (see chapter ‘Cleaning’).
You haven’t removed all packaging material from the filters. Make sure that
you have removed all packaging material.
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) HEPA filter, 2) activated carbon filter, 3) formaldehyde
filter (supplied with AC4074) or multi-care filter (supplied with AC4072), 4)
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 chapter ‘Cleaning’).
The room in which you run the appliance is larger than 55m², which is the
maximum size at which this air cleaner can operate effectively.
The colour of the air
quality light ring and the
air quality light always
stays the same.
The air quality sensor is dirty. Clean the air quality sensor (see
chapter ‘Cleaning’).
There is not enough ventilation in the room. Open a window, to improve
the air circulation.
I need cleaner air because
I have an allergy.
You can change the air quality sensor sensitivity (see chapter ‘Using the
appliance’) to make the air cleaner clean the air even better.
English 21
4222.003.4042.1.indd 21 18-09-09 14:17
Page: 21
Problem Possible solution
The appliance is extra
loud.
You haven’t removed all packaging material from the filters. Make sure that
you have removed all packaging material.
The appliance still
indicates that I need
to replace a filter, but I
already did.
Perhaps you did not press the filter reset button properly. Plug in the
appliance, press and hold the on/off button and press the filter reset button
with a flat tool.
The appliance stops
operating, although the
power-on light is still on.
The built in quality sensor has determined that the air quality is good and
