PRODUCT PARAMETERS
WORKING PRINCIPLE
Deerma humidifier uses ultrasonic waves to produce 1.7
million high-frequency oscillations every second, atomiz-
ing water into 1-5 microns ultra-fine particles. These pa-
rticles are then diffused into the air through a pneumatic
machine to give a uniform air humidification effect. This
machine is designed to keep your room at desired hum-
idity and prevent static electricity.
