To activate Auto Mode on your GermGuardian AC4880G, press the Power/Fan Speed button to turn the unit ON. The air purifier will start in Auto Mode by default, and the display will show an "A" for 5 seconds before switching to the Air Quality Index (AQI). While in Auto Mode, the fan speed adjusts automatically based on the air quality detected. If higher particle levels are detected, the fan speed will increase; once the air quality improves, the fan speed will lower. You can keep the unit in Auto Mode 24/7 for best results. To exit Auto Mode, press the power button again to cycle through the other fan speed settings.
