Up for review today is an all-in-one gadget by SoundSoul that functions as a humidifier, air purifier, night light and an essential oil diffuser for aromatherapy. The diffuser comes with an AC adapter, measuring cap, and manual.
What is great about having an ultrasonic humidifier is that water is not burned or heated. The SoundSoul ultrasonic humidifier creates an ultrasonic vibration frequency of 2.4Mhz which generate a fine mist which then diffuses through a spout at the top of the diffuser.

The humidifier has a built-in shut-off safety feature that turns the humidifier off when there is not enough water in the tank.
It's easy to use. Simply twist the cap counterclockwise, pour water (and essential oil) and hold the Mist button for 3 seconds.
The brightness of each color-changing LED light can be adjusted or completely turned off. The electricity consumption is minimal (~10watts), while the capacity of the water tank is 180ml. There is a timer feature that allows you to automatically turn off the diffuser in 60, 120 or 180 minutes, or you can keep the diffuser in the ON setting constantly (simply press the Mist button until the red LED lights up the ON setting)
The Verdict
The ultrasonic humidifier aromatherapy diffuser by SoundSoul has four functions: air purification, humidification, aromatherapy and nightlight. The device works great for distressing, eliminating odors and making your home smell lovely instantly in seconds. The humidifier itself is whisper quiet and the auto shut-off safety feature is great as it means you won't have to worry about turning the diffuser off when the water tank is empty.
