Eco Operation
In the eco operation mode, the unit automatically pauses when the air in the room is clean to save money on electricity. Furthermore, if this state continues more than 8 hours, the unit automatically stops operation. (In humidifying operations, the unit will not pause at a certain humidity level.)

The degree of air contamination is detected by the odor sensor and dust sensor during eco operation. If the sensors detect odor or dust, the airflow rate switches according to the degree of air contamination. When the air becomes clearer and the unit runs for 10 consecutive minutes or longer at “Silent” airflow, the unit starts intermittent operation.
