Air, like water, can be used for therapeutic massage. Arctic Spas® offers an available therapy air package on all spas. We start with a powerful air blower that forces soothing, heated air out of multiple air jets throughout the spa. Therapy Air provides a gentle, bubbling massage that makes you tingle from head to toe. Unlike most other spas that draw cold air from the outside, Arctic Spas® Therapy Air System draws warm air from the heated air space under the spa providing a warm and comfortable massage.
