4 Using the appliance

Understanding the air quality light

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

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 air quality sensors select the color that corresponds to the surrounding air quality of airborne particles.

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.

PM2.5 level Air quality light color
≤35 Blue
36-75 Blue-purple
76-115 Purple-red
>115 Red

|AI

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

8 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.	·Check if the top cover is properly installed.·The filter replacement light 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 reset the filter lifetime counter.
The airflow that comes out of the air outlet is significantly weaker than before.	·The pre-filter is dirty. Clean the pre-filter (see the chapter "Cleaning").
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 filters.·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: 1) NanoProtect filter Pro S3 (FY4152); 2) 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 the chapter "Cleaning").
The color of the air quality light always stays the same.	·The air quality sensor is dirty. Clean the air quality sensor (see the chapter "Cleaning").

Problem Possible solution

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 filters, 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.	· If the appliance is too loud, you can change the fan speed to a lower fan speed level. When using the appliance in a bedroom at night, choose the silent speed.
The appliance still indicates that I need to replace a filter, but I already did.	· Perhaps you did not reset the filter lifetime counter. Switch on the appliance. Then touch and hold the reset button ( ↗) for 3 seconds.
