Young Living's Essential Oil Diffuser gives you the benefit of diffusing essential oils throughout your home or office. Diffusing is a simple and effective way to use essential oils. With Young Living's innovative air pump, oils are dispersed in a micro-fine vapor, allowing them to remain suspended in the air for extended periods of time. The diffuser disperses the oils without heating them so they retain their therapeutic benefits. When inhaled, the oils are easily absorbed through the lungs. Depending on the oil used, diffusing can cleanse the air of odor, calm overactive children, and support respiration. Note: This is only the well and jet. It is not a complete diffuser.
