What are the types of aromatherapy machines

　　Ultrasonic aroma diffusers (also called humidified aroma diffusers) create a fine mist that mixes with the air. The function of the humidifying aromatherapy machine is to use ultrasonic waves to vibrate a small disc immersed in some kind of liquid, usually with water, and the vibration speed is very fast.

　　Atomizing Aroma Diffuser

　　This type of diffuser is a waterless diffuser that uses a pressurized airflow from a specially designed nozzle to break down essential oils into very small particles.

　　Air-blown aroma diffuser

　　Air diffusers use airflow to diffuse essential oils. A built-in fan blows air over a filter, stone or mat, allowing the essential oils on it to drift away.

　　Heated Aroma Diffuser

　　Just like the air-blown aroma diffusers mentioned earlier, heated aroma diffusers with built-in heat sinks allow essential oils to evaporate at a higher rate.
