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.

Air quality light color Air quality level
Blue Good
Blue-purple Fair
Purple-red Poor
Red Very poor

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  articles 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.

PM2.5 level Air quality light color
≤12 Blue
13-35 Blue-purple
36-55 Purple-red
>55 Red

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

IAI level Air quality light color
1-3 Blue
4-6 Blue-purple
7-9 Purple-red
10-12 Red

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

Gas level Air quality light color
L1 Blue
L2 Blue-purple
L3 Purple-red
L4 Red

Troubleshooting

This chapter summarizes 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 Center in your country.

Problem Possible solution
The appliance does not work even though it is plugged in. •  The filter

replacement alert has been on continuously but you have not replaced the corresponding filter. As a result, the appliance is now

locked. In this case, replace the filter and long press    to reset the filter lifetime counter.

The airflow that comes out of the air outlet is significantly weaker than before.| •  The surface of the filter is dirty. Clean the surface of the filter (see the chapter “Cleaning and maintenance”).

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 instances, smoking, cooking, incense, perfume or alchohol.

•  Filter reaches the end of life. Replace the filter with a new one.

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 filter, contact your Philips dealer or an authorized Philips

service center. The filter may produce 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.
