Portable USB humidifier for travel and desk use

The MAXI-MATIC HDC411 is a compact cool-mist humidifier with a 300 ml water tank that runs from any USB power source. Its 3.1 by 3.1 by 4.6 inch footprint and 0.141 kg weight make it practical for bedrooms, offices, cars or overnight trips.

White stainless-steel body

The egg-shaped housing uses stainless steel and a white finish, measuring 3.34 by 3.34 by 4.84 inches. A single button cycles through continuous mist, intermittent mist and the colour-light mode; holding the button for three seconds toggles the cycling LEDs independently.

Whisper-quiet ultrasonic operation

Ultrasonic technology keeps noise at 26 dB during use. Continuous mode runs for four hours and intermittent mode for eight hours before the automatic shut-off activates when the water level drops low.
