Each purchase of our Electric Diffuser comes with a FREE 30ml bottle of fragrance oil. Our diffusers are the perfect addition to any home, emitting a warm, color-changing glow when turned on. You have the option to choose any color or no color at all. Enjoy the relaxing ambiance at night with peace of mind, as the diffuser will automatically turn off when the chamber is empty, eliminating the need for open flames. Simply fill the chamber with water and a few drops of fragrance oil, switch it on, and your home will be filled with a delightful aroma in no time.
