2.2 Ultra-sound technology

Very dry air increases susceptibility to infection and respiratory diseases and leads to fatigue and lack of concentration. Healthy air should have a relative atmospheric humidity of 40 to 55% . The quiet, energy-saving ultrasound technology of the personal humidifier uses oscillation to convert water into a fine mist that increases the moisture level of the air. This improves the air quality and prevents the mucous membranes and skin from drying out. The capacity of the device is suitable for a room with a maximum area of 30~m^2 . Pay special attention to the notes on cleaning and care.

CAUTION

Over-intensive operation can result in saturating the room with moisture, which can affect the walls, windows and objects in the room. Therefore, use a hygrometer at regular intervals to check that the level of relative air humidity does not exceed 55% .
