Essio is a unique patented aromatherapy diffuser from Aromatec, Inc. that slowly diffuses essential oils into your shower. The arm can be installed on any standard showerhead. An essential oil pod attaches securely to the end of the arm via a quarter-turn bayonet mount. The user may then adjust the telescoping arm to position the pod in front of the showerhead into the water stream. The pod swivels up and down on a separate hinge to allow the user to adjust the flow of oil to their desire for a relaxing aromatherapy experience. When finished, the user may simply tilt the bottle upward to stop the flow of oil.
