User-friendly control panel provides function modes such as auto / manual / turbo. In auto mode, AP60 Pro continually monitors the air quality with intelligent sensor technology (sensors for fine dust, gas, odors) and automatically controls the power. In turbo mode, AP60 purifies the indoor air in a short period of time. In addition to the automatic and turbo adjustment, the fan speed can be manually adjusted at 3 levels with a separate super-quiet night mode. Timer function can be preset to a run time of 1, 2, 4, or 8 hours. Child-proof lock function. The current operational state is displayed. AP60 Pro automatically informs when to change the 360° filter by showing a red “F“ on top of the device. On average, the 360° filter has to be changed after 12 months, depending on the intensity of the usage.
