Fusion Air Sound System
Set the mood for your swim or recovery session with the Fusion Air Sound System, available on any Michael Phelps Signature Swim Spa model. Four water-resistant speakers and a subwoofer provide balanced sound, while Bluetooth connectivity makes it easy to stream music, podcasts, or entertainment from your device. It's a simple way to bring sound into your swim spa experience — whether you want motivation, relaxation, or something in between.
Water Management System
The Mast3rPur™ Water Management System is a synergistic blend of three proven natural water sanitizers that, when combined, creates a chemical reaction known as Advanced Oxidation Process. This results in clean, clear, fresh-smelling and silkier water. The Mast3rPur™ option comes equipped with the QuietFlo Water Care System, a 24-hour circulation pump.
Mast3rPur Water Management System comes standard on the MP Signature Pro.
Mast3rPur is available only in the USA and Canada. In other regions, Michael Phelps Signature Swim Spas feature the QuietFlo Water Care System as a premium option.
