Important

• Read the instructions carefully before you

start using the appliance.

• Never immerse the appliance in water or

any other liquid.

• Do not use the appliance outside or in a

humid environment. 

• The appliance influences the air

circulation in the room in which it is used.
It is recommended not to use the
appliance next to an open fire.

• Always remove the plug from the wall

socket before you open the appliance or
before you start cleaning it.

• Do not touch any moving parts when you

open the appliance. Let the Rota filter
come to a halt by itself.

• Keep the cord away from hot objects.
• If the cord of this appliance is damaged, it

may only be replaced by an authorised
Philips service centre, since repair
requires special tools and/or parts.

Additional measures

• In urban areas: keep your windows closed

during the hours in which there is a lot of traffic
and when factories etc. are polluting the air.

• Vacuum clean your house regularly. Hard floors

are better than carpets.

• Use mite-proof coverings and sheets to limit the

amount of house dust allergens coming out of
mattresses and blankets. 

How does the Philips air cleaner work?

The air cleaner sucks in air though its front and
both sides. The sucked-in air is filtered by the air
cleaner. After filtering, clean air is blown out from
the top of the appliance. To be able to remove
even the smallest particles from the air, the air
cleaner has been equipped with a unique three-
stage filter system.

1

Prefilter

The washable prefilter catches the larger airborne
particles, such as fluff, hairs, etc.

2

Rota filter

This rotating filter catches particles of down to 
2 microns in size (for instance pollen). When a
particle enters one of the ducts of the filter, it is
pressed to the wall of the duct as a result of the
centrifugal force. The air is allowed to pass
through the duct while the particle remains behind
in the filter. The Rota filter is washable.

3

HEPA filters

Finally, the HEPA filters remove all remaining
particles from the air, small particles in particular.
The filter is made of glass fibres which are packed
so closely together that they prevent even very
small particles from passing through the filter. The
same type of filter is also used in most operating
rooms in hospitals.

English

Clean air in your house is a prerequisite for the
prevention of inhalant allergies. Your Philips air
cleaner will help you remove airborne particles
from the air effectively. These particles also
include allergens, such as house dust, pollen and
pet allergens as well as viruses, bacteria and
mould spores.

When comparing air cleaners you will notice that a
number of terms are used by suppliers as an
indication of the effectiveness of their appliances.
The standard that best reflects the effectiveness
of an air cleaner is CADR (Clean Air Delivery
Rate). In general, an air cleaner with a high CADR
will remove particles from the air more quickly
than an air cleaner with a low CADR.
