The Ultrasonic Digital humidifier is the crown jewel of Germ Guardian’s new humidifier series. I had the opportunity to take the Ultrasonic Digital home with me to test the unit in my daughter’s bedroom. The best feature of the humidifier is how quietly it operates. On the highest setting, the Ultrasonic Digital is almost silent. My daughter was able to sleep comfortably with the humidifier running in her bedroom. After setting the digital clock, I had the ability to set a timer to start and stop the humidifier while she slept.

One other area where this humidifier shines is the amount of control given to the user. The Ultrasonic Digital allows for exceptional control over the humidity output. Besides the timer function, I was able to control the power, the direction, and the temperature of the spray. The buttons and the digital display are easy to navigate. The display is fun to use and the graphics are simple to follow. Each function is controlled with large, readable buttons. The four speed settings—low, medium, high, and turbo--are displayed as colored lights that encircle the clock, and I was able to control the speed with a simple push of a button. With the spout on top of the unit, I could control the direction of the spray. The one drawback I could find was that the temperature control did not seem to generate a very warm spray. As with other humidifiers, you want to make sure this unit is up off the floor. Otherwise you may find the surrounding area damp in the morning.

My daughter really liked the night light feature. A soft ring of light encircles the front of the humidifier. The light (which can be turned on or off) is stylish and is bright enough to provide a comfortable glow in any child’s room.

The Ultrasonic Digital is bigger in size than some other humidifiers I have tested this year. The dimensions are 14.5 x 9 x 12 inches. This humidifier has a 1.4 gallon tank capacity which yields about three days of continuous use. With the Ultrasonic Digital I was able to tailor the output to fit my daughter’s needs and her sleep habits. The Ultrasonic Digital has a funky, retro design combined with optimal user control.
