English
To prevent respiratory problems, clean air in your home is a
basic requirement.
Your Philips Air Cleaner helps you to purify the air effectively
by catching up to 99% of the airborne particles.
This includes allergens such as house dust and pollen as well
as viruses and bacteria.
None of these particles are useful for the human body.
Some of them are actually very harmful and may cause serious
complaints and diseases.
The particles vary in size from 0.1 to 100 micron (1 micron =
0.001 mm).
Additional measures
• In the urban environment: Keep the windows closed during
the hours when there is heavy traffic or when factories etc.
pollute the air.
• Vacuum regularly. It is better to have hard floors instead of
carpets.
• Furry pets increase respiration problems, so it is best not to
keep furry pets.
• Apply special bedding to reduce dust production by
matrasses and blankets.
How does the Philips Air Cleaner work?
The Air Cleaner takes air from near the floor where particles
concentrations are greatest and after cleaning blows it towards
the ceiling.
To remove even the smallest particles from the air, the
appliance employs a unique 3-stage Air Cleaner filter:
Pre-filter
The Pre-filter catches the larger dust particles floating in the
air, such as fluff and hairs.
Rota filter
The rotating disc filter takes out the particles of 2 micron and
more (e.g. pollen).
On entering one of the channels of the filter a particle is
centrifuged against the side of this channel.
The air will pass through the channel but the particle remains
stuck against the channel wall.
This unique and patented filter ensures a long life for the Hepa
filters.
Hepa filter
The last filter is the Hepa filter.
This filter takes out all the remaining smaller particles.
The filter is made from glass fibres closely matted such that
particles cannot pass through.
Similar filters are used in most hospital operating rooms.
This Air Cleaner can be set to automatically select the correct
speed of air cleaning.
The appliance is equipped with a 24-hour clock and a timer
which make it possible to select one period a day during which
the appliance switches on and off automatically.
An indicator light will light up when the Hepa filters need
replacement.
Positioning
1
• In general, it is advisable to place the Air Cleaner in a central
position, with its rear side against the wall and standing on
the floor (fig. 1 - 2).

• The Air Cleaner can also
be wall-mounted (fig. 3 - 4).
Select a position similar to
fig. 1.
Do not mount it higher than
10 cm above the floor.
• It is also possible to place
more than one Air Cleaner
in the same room. This is
especially advisable if the
room is very large and/or
has an irregular shape. In
such a case it is best to
place the appliances as far
apart as possible but
against the same wall.
• Never obstruct the air inlet
or outlet openings (fig. 5).
• When using heating
appliances: place the Air
Cleaner so that the air
stream it generates
coincides with the
convection air stream
produced by the heater.
