With this new bedroom air purifier you breathe cleaner air. For the best results, place the bedroom air purifier 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 purifier 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 bedroom air purifier has a unique multi-stage filtration system that ensures 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: 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.

- Stage 3: The Activated carbon filter filters out odours and harmful gases effectively.

- Stage 4: The high-performance composite HEPA filter with antibacterial coating effectively filters out fine dust and cigarette smoke, while the antibacterial and anti-mould functions of organic antibacterial materials filter 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.

Auto mode

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.

1 Press the on/off button to switch on the appliance.

- The appliance automatically starts operating in the auto mode.

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.

Adjusting the air quality sensor sensitivity

People with certain health problems (e.g. allergies or asthma) have a greater need for healthy air. For this reason, the air purifier 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:

• 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.
- The appliance beeps twice and one of the HOUR lights flashes to show the current sensitivity level of the air quality sensor.
