This is a small cylindrical humidifier that runs off USB power and puts out a cool ultrasonic mist at roughly 40 to 45 ml per hour, with two spray settings and a mechanical control. It holds under a liter of water and includes a filter stone meant to absorb impurities as it moisturizes. It suits a desk, nightstand or hotel room where you want a little local moisture without a full-size appliance. Against larger ultrasonic humidifiers it trades room-scale output and run time for portability and simple power; there is no auto shutoff or humidity sensor listed.
