Nebulizing Diffuser (from France) features silent operation and an output control that easily diffuses over a 300–600 square-foot area. Our diffuser ionizes undiluted essential oils into an ultra-fine vapor that remains suspended in the air for maximum availability and minimum waste. In addition, it features a convenient on/off switch, is easy to clean, and is designed with a glass injector so that oils do not come into contact with any metal parts.
