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.

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.

22 ENGLISH

Troubleshooting
	This chapter summarises the most common problems you could encounter with the appliance. If you are unable to solve the problem with the information below, contact the Consumer Care Centre in your country.
Problem Possible solution
The appliance doesn't work.	You ignored the filter replacement lights. You did not replace a filter when the corresponding filter replacement light and the REPLACE FILTER light started flashing and did not respond when the appliance started to beep every 30 minutes after approx. 2 weeks. As a result, the appliance is now locked and you have to replace the filter and reset the appliance (see chapter 'Filter replacement') so that the appliance can provide healthy air again.
The AIR QUALITY lights keep flashing and the appliance does not work.	There is a problem with the air quality sensor of the appliance. Please contact the Philips Consumer Care Centre in your country (you find its phone number in the worldwide guarantee leaflet). If there is no Consumer Care Centre in your country, go to your local Philips dealer.
No air comes out of the air outlet	The appliance is not switched on. Put the plug in the wall socket and switch on the appliance.The air quality is good and the auto mode is activated. In this case, the appliance stops operating automatically when the air is clean to save electricity.
The airflow that comes out of the air outlet is significantly weaker than before.	The pre-filter is dirty. Clean the pre-filter (see chapter 'Cleaning').You haven't removed all packaging material from the filters. Make sure that you have removed all packaging material.
The air quality does not improve, even though the appliance has been operating for a long time.	One of the filters has not been placed in the appliance. Make sure that all filters are properly installed in the following order, starting with the innermost filter: HEPA filter, Activated carbon filter, Multi-care filter (AC4004 only), pre-filter. The Multi-care filter (AC4004 only) has to be attached to the back of the pre-filter.The air quality sensor is wet. The humidity level in your room is high and causes condensation. Make sure that the air quality sensor is clean and dry (see chapter 'Cleaning').
The AIR QUALITY light does not change colour even though the appliance has been operating for some time.	The air quality sensor is dirty. Clean the air quality sensor (see chapter 'Cleaning').
I need cleaner air because I have an allergy.	You can change the air quality sensor sensitivity (see chapter 'Using the appliance') to make the air purifier clean the air even better.
The appliance is extra loud.	Please check if you have removed all the packaging material from the filters.If the appliance is still too loud, you can change the fan speed to a lower fan speed level.

Problem Possible solution

The appliance still indicates that I need to replace a filter, but I already did.	Perhaps you did not reset the appliance. Plug in the appliance, press and hold the reset button corresponding to the filter you have replaced. The appliance beeps if you have reset it properly.
When I press the SLEEP button, all lights except for the SLEEP light go out.	When you press the SLEEP button, the appliance enters the SLEEP mode, which is designed to allow you to sleep undisturbed. The appliance operates quietly and only the SLEEP light is on. If you have activated the timer, one of the HOUR lights is also on. All lights that are on in the SLEEP mode are dimmed to allow you to sleep undisturbed.
The appliance stops operating, although the power-on light is still on.	The built in quality sensor has determined that the air quality is good and that the air does not need to be cleaned anymore.

Problem Possible solution
The appliance doesn't work.	You ignored the filter replacement lights. You did not replace a filter when the corresponding filter replacement light and the REPLACE FILTER light started flashing and did not respond when the appliance started to beep every 30 minutes after approx. 2 weeks. As a result, the appliance is now locked and you have to replace the filter and reset the appliance (see chapter 'Filter replacement') so that the appliance can provide healthy air again.
The AIR QUALITY lights keep flashing and the appliance does not work.	There is a problem with the air quality sensor of the appliance. Please contact the Philips Consumer Care Centre in your country (you find its phone number in the worldwide guarantee leaflet). If there is no Consumer Care Centre in your country, go to your local Philips dealer.
No air comes out of the air outlet	The appliance is not switched on. Put the plug in the wall socket and switch on the appliance.The air quality is good and the auto mode is activated. In this case, the appliance stops operating automatically when the air is clean to save electricity.
The airflow that comes out of the air outlet is significantly weaker than before.	The pre-filter is dirty. Clean the pre-filter (see chapter 'Cleaning').You haven't removed all packaging material from the filters. Make sure that you have removed all packaging material.
The air quality does not improve, even though the appliance has been operating for a long time.	One of the filters has not been placed in the appliance. Make sure that all filters are properly installed in the following order, starting with the innermost filter: HEPA filter, Activated carbon filter, Multi-care filter (AC4004 only), pre-filter. The Multi-care filter (AC4004 only) has to be attached to the back of the pre-filter.The air quality sensor is wet. The humidity level in your room is high and causes condensation. Make sure that the air quality sensor is clean and dry (see chapter 'Cleaning').
The AIR QUALITY light does not change colour even though the appliance has been operating for some time.	The air quality sensor is dirty. Clean the air quality sensor (see chapter 'Cleaning').
I need cleaner air because I have an allergy.	You can change the air quality sensor sensitivity (see chapter 'Using the appliance') to make the air purifier clean the air even better.
The appliance is extra loud.	Please check if you have removed all the packaging material from the filters.

Problem Possible solution

	• If the appliance is still too loud, you can change the fan speed to a lower fan speed level.
The appliance still indicates that I need to replace a filter, but I already did.	Perhaps you did not reset the appliance. Plug in the appliance, press and hold the reset button corresponding to the filter you have replaced. The appliance beeps if you have reset it properly.
When I press the SLEEP button, all lights except for the SLEEP light go out.	When you press the SLEEP button, the appliance enters the SLEEP mode, which is designed to allow you to sleep undisturbed. The appliance operates quietly and only the SLEEP light is on. If you have activated the timer, one of the HOUR lights is also on. All lights that are on in the SLEEP mode are dimmed to allow you to sleep undisturbed.
The appliance stops operating, although the power-on light is still on.	The built in quality sensor has determined that the air quality is good and that the air does not need to be cleaned anymore. When the air quality deteriorates, the appliance is starts running at a low fan speed and noise level so that the energy consumption is minimised.
The appliance does not work. The air quality light ring flashes blue, all other lights are out.	This is air particle sensor error or an air particle sensor and gas sensor error.
