If you are diffusing your oils using heat, you may be denaturing it and ruining its efficacy. Real diffusers use ultrasonic vibrations to break oils and water into microscopic particles which are then released into the air. This particular diffuser can operate up to 6 hours on one fill and has optional RGB mood lighting. With adjustable misting strength and duration settings, you can adjust the function to ensure the perfect saturation no matter your oil of choice.
