The Soto diffusers have colour changing mood lighting, which easily moves through a rainbow of colours, or can be set on a single colour of choice. They also have a no light option, to continue soothing whilst you sleep.
The Soto aroma diffusers also act as mini humidifiers. They create a cool, scented and relaxing mist which will spread fragrance quickly and effectively.
The Soto is easy to use. It requires tap water and a few drops of your favourite fragrance or essential oil
