#4 How can I tell if my air is clean?
The illuminated air quality ring on the front display will change color as your air quality changes. The color of the ring indicates the air quality: Blue = Good air quality, Amber = Fair air quality, Red = Poor air quality. By pressing the AIR INFO button on your unit, you can switch between air quality info options. These include percentage of clean air, estimated time until the air will be clean, and the estimated number of PM1.0, PM2.5, and PM10 particles in the air surrounding the unit.
Other air purifier settings include fan speed, brightness, timer, filter life, child lock, and AUTO mode. When enabled, the AUTO mode setting automatically adjusts the fan speed of your air purifier based on the air quality. (If the air quality decreases, the fan speed will increase.) To activate AUTO mode, select the AUTO button on the top control panel. When this option is selected, the AUTO button will appear brighter than the other buttons. To turn off AUTO mode, press the AUTO button again or manually change the fan speed.
