A diffuser is a device used in aromatherapy to disperse essential oils into the air, creating a pleasant and therapeutic atmosphere. By using water and heat or ultrasonic vibrations, diffusers break down the oils into tiny particles, allowing them to be inhaled easily. This process can enhance mood, promote relaxation, and improve overall well-being. There are various types of diffusers, including ultrasonic, nebulizing, and heat diffusers, each with its own method of operation. Many people use diffusers in their homes, offices, or wellness spaces to enjoy the benefits of essential oils like lavender, peppermint, or eucalyptus.
