How It Works: Ultrasonic vibrations create microparticles from the tap water and fragrance or essential oils placed inside the diffuser. These microparticles then dissipate into the environment and provide all of the energy and mood-boosting benefits of the chosen oils. Why It Works: Our diffusers do not use heat which can ruin the makeup of therapeutic oils and reduce their benefits. Ultrasonic technology preserves the quality and chemical structure of the oils.
