Too dry air will quickly cause rough skin, irritation of the eyes or difficulty breathing. According to some studies, pathogens can survive longer in dry air. Therefore, experts recommend a humidity of at least 40% at a normal room temperature of 20 to 22C. This practical air humidifier uses ultrasonic waves to generate fine cold mist to fill the indoor air with moisture. The diffuser operates very quietly and has very little noise, so it is very suitable for use in the living room or office, bedroom or children's room. Using the built-in timer, you can select 1 hour, 3 hours or 6 hours of working time. If necessary, the room humidifier can be filled with essential oils to fill the room with a pleasant fragrance.
