Using the air purifier

Understanding the air quality light

The air quality light automatically goes on when the air purifier is switched on and lights up all colors in sequence. After approximately 30 seconds, the particle sensor selects the color that corresponds to the surrounding air quality of airborne particles.
The color of the air quality light is determined by the highest risk index among PM2.5, IAI, and Gas readings.

PM2.5

AeraSense sensing technology accurately detects and quickly responds to even the slightest particle change in the air. It provides you with reassurance with real-time PM2.5 feedback.
Most of the indoor air pollutants fall under PM2.5 – which refers to airborne particle pollutants smaller than 2.5 micrometers. Common indoor sources of fine particles are tobacco smoke, cooking, burning candles. Some airborne bacteria and the smallest mold spores, pet allergen, and dust mite allergen particles also fall under PM2.5.

IAI

The professional-grade AeraSense sensor detects the level of indoor air allergens and with numerical feedback from 1 to 12, the potential risk level of indoor air allergens can be displayed. 1 indicates the best air quality.

GAS
With an advanced gas sensor, a display ranging from L1 to L4 shows the level change of potentially harmful gases (inc. VOC, odor, etc.) detected. L1 indicates best air quality.

The air quality does not improve, even though the appliance has been operating for a long time.|

• Check if the packing material is removed from the filter.

• The filter has not been placed in the appliance. Make sure that the filter (FY4440/30) is properly installed.

• The particle sensor is wet. The humidity level in your room is high and causes condensation. Make sure that the particle sensor is clean and dry (see the chapter “Cleaning and maintenance”).

• Room size is large or the outdoor air quality is poor.
  For optimum purification performance, please close the doors and windows when operating the air purifier.

• There are indoor pollution resources. For instance, smoking, cooking, incense, perfume or alchohol.

The color of the air quality light always stays the same.|

• The particle sensor is dirty. Clean the particle sensor (see the chapter “Cleaning and maintenance”).

The appliance produces a strange smell.|

• The first few times you use the appliance, it may produce a plastic smell. This is normal. However, if the appliance produces a burnt smell even if removing a filter, contact your Philips dealer or an authorized Philips service center. The filter may produce a smell after being used for a while because of the absorption of indoor gases. It’s recommended that you reactivate the filter by putting it in direct sunlight for repeated use. If odor still exists, replace the filter.

The appliance is extra loud.|

• It’s normal if the appliance runs at the Turbo mode.
• In the Auto mode, if the appliance is too loud, maybe the appliance runs at high speed because air quality becomes worse, or your personalized setting in App triggers a higher fan speed. You can choose the Sleep mode, or change the settings in the App.
• If there is an abnormal sound, contact the Consumer Care Center in your country.
• If anything drops into the air outlet, it may also cause abnormal loud sounds. Immediate turn off the appliance, turn appliance upside down, to get foreign objectives out of the appliance.
