A diffuser is a device used in aromatherapy to disperse essential oils into the air, creating a pleasant and therapeutic atmosphere. By breaking down the oils into tiny particles, diffusers help to enhance the aroma and benefits of the oils, promoting relaxation, focus, or other desired effects. There are various types of diffusers, including ultrasonic, nebulizing, and heat diffusers, each using different methods to release the oils. Many people use diffusers in their homes, offices, or wellness spaces to improve air quality and create a calming environment.
