The blissful combination of water, heat and air movement creates an incomparable effect that is as therapeutic as it is relaxing. The movement of millions of tiny air bubbles activates the lymphatic systems, increases blood flow, stimulates endorphins and relieves sore muscles and other painful ailments. MTI offers two unique air systems: Air Massage and Air Massage Elite. Both provide a full-body massage experience via 20 or 30 air jets located in the bottom of the bathing well. Because of its gentle massage action, the air bath may be particularly well suited for the elderly.
