How It Works: Ultrasonic vibrations agitate the simple combination of tap water and a few drops of fragrance or essential oils, to create microparticles that are released into the environment. This method maintains the properties of the scented oils, unlike methods that use heat. Why It Works: High temperatures result in damage to the chemical structure of a therapeutic oil, reducing the potency and hampering its effectiveness. Our ultrasonic technology provides our wholesale aroma diffusers optimal quality. Features: Easy to Use 100 ML 7 Color LED Lights
