Fan Fuser Aromatherapy DiffuserWe love the Fanfuser for its ease of use and effectiveness. It's quiet and safe, which makes it a nice choice for retirement homes, galleries and stores. The Fan Fuser uses no heat and requires no candle or glass. To use, simply add a few drops of essential oil or aromatherapy blend to the replaceable pad, plug the Fan Fuser into any 110 volt wall outlet and flip the switch to high or low. You'll be surrounded with a gentle breeze that carries the aroma throughout the room. The Fanfuser has high and low speeds, and unlike the nebulizer diffusers, works well with both thin and thick oils. You can also use several oils at the same time, mixing your own blend. This diffuser works well in a space up to around 500 square feet. Includes two fragrance pads. Extra replacement pads available. Add timer for more versatile use.
