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:
❶Pre-filter
The Pre-filter catches the larger dust particles
floating in the air, such as fluff and hairs.
❷Rota 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

English for the Hepa filters.
Moreover, their overall performance will remain
virtually constant over the life of the filters.
❸Hepa 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.
Positioning
• 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.
This means: Position the Air Cleaner near the
radiator or other source of heating (fig. 6 - 7).
• Especially for allergic users it is advisable to
use an Air Cleaner in both the bedroom and the
living room and to let these run continuously.
Which size of Air Cleaner is suitable?
To purify effectively the air in a domestic room or
an area of a room, all the air must pass the Air
Cleaner filters 2 - 3 times per hour.
Depending on the air contents of the room or area
concerned:
• one Air Cleaner type HR 4320 should be used
for rooms / areas up to approx. 30 m2floor
surface);
• one Air Cleaner type HR 4330 should be used
for rooms / areas up to approx. 50 m2floor
surface).
