My smart modes

With the smart mode function, the Coway Airmega automatically adapts its surroundings and adjusts the fan speed to the room air quality.

Intelligent car mode

The smart mode changes the fan speed and switches on the ECO mode based on the air quality in real time. This improves the efficiency of the device and saves energy.

Intelligent Eco mode

The ECO mode switches on automatically when the room stays clean for 10 minutes. The blower is switched off to save energy and switches on again as soon as the air quality deteriorates.

Smart mode/sleep mode

If the integrated light and air sensor detects darkness for 3 minutes with optimal air quality, it automatically reduces the fan speed to reduce the running noise and save energy. The sleep mode can also be activated manually.
