The Dew Drop is the perfect combination for both aromatherapy and humidity control. Its attractive artistic design fits into most decors, whether at home or office. The ultrasonic design fills your room with an ultrafine mist which will allow for our essential oils to be suspended in the air for longer periods of time and for better inhalation. This process does not heat essential oils, keeping their holistic properties intact. The Dew Drop uses tap water as well to keep things simple. Four rotating LED lights create a soft soothing color changing effect or turn off the lights altogether.
