What is VOC Auto Sensing mode and how does the LED indicator work?

VOC Auto Sensing mode uses the AirGenius 6's built-in sensor to automatically adjust the cleaning level based on detected Volatile Organic Compounds in the room. The circular LED display glows green for low VOC levels (Sleep setting), amber for moderate levels (General setting), and red for high levels (Max setting). The unit continuously monitors VOC levels and adjusts accordingly. (Page 3)
