The MUJI Aroma Mist Humidifier combines functionality with style, creating a humidification system that makes your living space more comfortable. It features an aromatherapy function and automatically shuts off when the water is gone to prevent overheating. Built-in light allows for creating a relaxing environment at night, as well. The ultrasonic atomization releases negative ions into the air to improve air quality and create a clean living space by removing dust and bacteria from the air.
