After use, pull out the mains plug and empty the water tank, as well as pour out the remaining water in the base.
Clean the water tank with vinegar water. Leave the vinegar water in the water tank for 15 minutes to prevent limescale from forming. Limescale damages the ultrasonic plate of the humidifier.
Then rinse the tank with clear water and dry it with a soft cloth.
Clean the base with the ultrasonic plate in the same way with vinegar water.
It is absolutely necessary to regularly protect the ultrasonic nebuliser from limescale. Otherwise the limescale particles are excreted through the ventilation and leave stains on furniture, but above all the limescale damages the ultrasonic plate and the humidifier breaks down.
Limescale is the biggest enemy of an ultrasonic humidifier.
