Ultrasonic Humidifier Manual

We're experts in improving indoor air quality, and our ultrasonic humidifier will dissipate dryness and increase moisture wherever you choose to use it. To ensure optimal performance, please read this guide carefully before use. The ultrasonic humidifier atomizes water into ultra-fine particles using the principle of ultrasonic high-frequency oscillation, and diffuses water into the air through a pneumatic device to evenly humidify the air.
