Why choose us? The first thing you will notice when you power on this diffuser is the plume of mist that rises up, formed by the inside water droplets vibrating. This is perfect for small to medium sized rooms like a bedroom, dining, bathroom, especially if they are air conditioned or in winter which makes the air dry. Keeping your living space humid helps prevent colds/flu and congestion. Run your hand through the mist - it's cold. The oil isn't burned like a traditional diffuser meaning the aromatherapy benefits are retained in the oil. Now hit the light button. The diffuser transforms through 7 colors . Hit the light button again and it stays on the color of your choice. Features: Three Settings toggled by the Mist button: * Dynamic Orange Lights - intermittent mist (Mist 30 seconds and Pause 30 seconds) * Stable Orange Light - continuous mist * Off - You may use it as a color changing light without mist Auto shut off when water runs out. Keep essential oil 100% natural without burning or heating.
