AirJet™ is the massage system found in the majority of SaluSpa inflatable hot tubs — and understanding how it actually works helps you buy with confidence rather than guesswork. Unlike water-based jet systems, AirJet™ works by pumping heated air through dozens of small outlets positioned around the base and lower walls of the tub.
That air rises through the water as thousands of fine bubbles, surrounding every part of your body simultaneously. The result is a soft, enveloping full-body massage — consistent across the entire tub, from the first session to the hundredth. Every model in this category uses the AirJet™ system, heats to 104°F, and sets up in around 15 minutes with no tools required.
