The USB Portable Air Humidifier is very easy to operate. One button controls all functions, you simply need to press one button to set the mist and night light.
- The USB Portable Air Humidifier provides constant moisture all night after filling, for up to 24 hours at low mist level and even 12 hours of high mist in the driest autumn and winter days.
- Have a full night’s undisturbed sleep, as the night mode keeps all lights including the tank light and LED indicators off, runs at the low mist, and mutes all touch buttons.
- The USB Portable Air Humidifier auto shuts off at a low water level to prevent dry running; protective nano-coating on the internal structure keeps it from dust and rust for a longer service time.
