LED light changes in real time, based on the air quality.

When the room's ambient light decreases, the WInix 5520 automatically enters Sleep Mode, dimming the LEDs and reducing fan speed for quieter operation. As the light levels increase, the 5520 returns to Auto Mode for continuous air purification.
