A diffuser breaks down fragrance oils and diffuses them into the air, creating a pleasant scent. At Doctor Aromas, we offer two types of diffusers: Aromatherapy Stone Diffusers Aromatherapy is the use of essential oils to create a pleasant scent. These diffusers can be placed in different areas of your home or business – wherever you’d like to increase the scent intensity or enjoy your favorite scent at all times. They come with a power adaptor and automatically turn off when they run out of water. Because they only use one drop of fragrance oil at a time, our stone diffusers offer a highly efficient scenting option that is a great way to enjoy the therapeutic benefits of aromatherapy. Oil Reed Diffusers This scenting system uses bamboo reeds to help diffuse essential oils, providing a natural way to create a pleasant smell that you can place anywhere in your home or office space. These oil diffusers don't use any electricity and last for a long time.
