Oil diffusers are devices that disperse essential oils into the air. They work by Simple heating or using ultrasonic technology to turn the essential oil and water mixture into a fine mist, which is then diffused into the air. The diffused oil aroma can provide benefits such as aromatherapy, relaxation, and mood enhancement. Oil diffusers come in various sizes and styles, ranging from small, portable units to larger, more decorative diffusers. Some oil diffusers also have additional features such as lighting and automatic shut-off. They are commonly used in homes, offices, and spas
