Mist Diffuser 130ml 130 ml capacity. 2 level mist control. Low water level cut off. Our essential oils will work perfectly with our ultrasonic diffusers. Choose from five aromatherapy blends to suit the needs. Vaporise- The ultrasonic diffuser/vaporiser makes ultrasonic vibrations through the water. These vibrations transform water into a cool vapour without the use of heat, ensuring the essential oils diffused are retained in their purest form and released in a fine mist. Humidify- The ultrasonic waves created by our diffusers stimulate moisture in the air to combat the drying effects of heating and air-conditioning, leaving your environment clean and comfortable. Purify- By releasing negative ions, the Diffuser purifies the air in a room of dust, bacteria, pollen and household odours. Illuminate- Your diffuser can move through a series of relaxing colours, with the option to set to the desired colour for a fixed period, or return to oscillation.
