Why does the AIR QUALITY light indicate bad air quality even though the air quality is good?

If condensation develops on the air quality sensor, it may cause the AIR QUALITY lights on the control panel to indicate bad air quality. You can solve this by cleaning the air quality sensor.

What does the auto mode do in the Philips Air Cleaner?

The built-in air quality sensor automatically measures the ambient air quality and selects the most appropriate fan speed for the measured air quality when the auto mode is activated.

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.
