With this new bedroom air purier you breathe cleaner air. For the best
results, place the bedroom air purier in a room where you spend most of
your time, e.g. the 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 bedroom air purier reduces the amount of animal dander
and industrial pollutants in the air, and therefore improves the air quality.
It also lters out ultrane particles larger than 20 nanometres, including
bacteria and some viruses. According to publications of the World Health
Organization, the avian and human inuenza viruses and the Legionella
bacterium are larger than 20 nanometres.

The bedroom air purier has a unique multi-stage ltration system that
ensures the best air quality:
- Stage 1: The pre-lter has been treated with antibacterial substances. It
catches big particles like human hair, pet hair etc.
- Stage 2 : In combination with the HEPA lter, the multi-care lter lters
out dust, pollen and ultrane particles larger than 20 nanometres,
including bacteria and some viruses. According to publications of the
World Health Organization, the avian and human inuenza viruses and
Legionella bacterium are larger than 20 nanometres.
- Stage 3: The activated carbon lter lters out odours and harmful gases
effectively.
- Stage 4: The high-performance composite HEPA lter with anti-
bacterial coating effectively lters out ne dust and cigarette smoke,
while the antibacterial and anti-mould functions of organic antibacterial
materials lter out germs and mould.

,The appliance automatically starts operating in the auto mode.
To switch off the appliance, press and hold the on/off button again until the
power-on light goes out and unplug the appliance.
Note: When the humidity level in the room is very high, it is possible that
condensation develops on the air quality sensor. As a result, the AIR QUALITY
lights on the control panel may indicate that the air quality is bad even though
the air quality is good. In this case, the auto mode causes the appliance to
run at high fan speed. You can solve this by cleaning the air quality sensor. If
condensation develops frequently during periods of high humidity, we advise
you to use one of the manual speed settings.

When the appliance is switched on, the built-in air quality sensor
automatically measures the ambient air quality. When the auto mode is
activated, the appliance selects the most appropriate fan speed for the
measured air quality.
Note: When you use the auto mode, you can also use the timer function (see
section ‘Timer function in this chapter). In this case, the AUTO light, one of the
FAN SPEED lights, the TIMER light and one of the HOUR lights are on.

Note: When the appliance is operating in another mode and you want to
activate the auto mode, simply press the AUTO button.
,The AUTO light and one of the FAN SPEED lights go on. The FAN
SPEED light indicates at which fan speed the appliance is operating.
Note: When the air quality is very good and the fan speed operates at a very
low fan speed, the FAN SPEED light for the lowest speed level does not go on.
In this case only the power-on light and the AUTO light are on.
Note: The built-in air quality sensor measures the air quality and automatically
selects the appropriate speed setting to ensure the best possible air quality in
your room. When the air is clean, the appliance stops running. When the air
quality deteriorates, the appliance starts running at a low fan speed and noise
level so that the energy consumption is minimised.

If you do not use the auto mode, you can select the desired fan speed

People with certain health problems (e.g. allergies or asthma) have a
greater need for healthy air. For this reason, the air purier allows you to
adjust the sensitivity of the air quality sensor. When it is set to a higher
sensitivity level, the appliance already starts cleaning the air at lower
pollution levels to make the air even cleaner.
There are 3 sensitivity levels:
 13

- extra sensitive
- sensitive
- standard
The air quality sensor is set to standard sensitivity. You can adjust the
sensitivity of the air quality sensor in the following way:
1 If the appliance is already plugged in, unplug the appliance and wait
for a few minutes.
2 Press and hold the TIMER button and simultaneously put the mains
plug in the wall socket.
