MTI thermo-air massage systems include an aromatherapy diffusion system to allow the bather to enjoy the benefits of this ancient form of therapy. (Except all freestanding models and MTI-3, MTI-9, MTDS-65 and MTDS-73).

MTI's aromatherapy diffusion system is easy to use, flexible and effective. A small deck-mounted well houses a removable canister which contains the user's fragrance of choice. When the thermo-air massage system is activated, the warm air produced by the blower passes through the canister. The scent is then carried by millions of air bubbles through the water to the surface of the bath water, where the bubbles pop and release the aroma. The scent fills the air, not the bath. Of course, if preferred, bath salts and oils may be added directly to MTI air bath water.

The design of MTI's aromatherapy system allows the use of a wide variety of pure essential oils, both singular fragrances as well as blends. MTI recommends the use of pure essential oils and blends manufactured by Aromaland, manufacturer of premium quality aromatherapy products. Pioneering aromatherapy since 1986, Aromaland is one of the oldest aromatherapy companies in the US. All fragrances are 100% natural and of the highest quality. All oils are carefully tested to ensure a pure product, maximum effectiveness and thorough enjoyment.
