The Hydrotherapy Massage System includes the Ozone Sterilization System. The sterilization system is the most eco-friendly, chemical free disinfectant that can eliminate a wide variety of inorganic, organic, and microbiological bacteria. It automatically engages when the hydrotherapy massage is activated. While the Ozone Sterilization System will not completely replace the need to clean your tub monthly, it is especially helpful in hygienic maintenance and eliminating odors in our one to two bather walk-in tub options.

Please Note: If you choose the Hydrotherapy + Independent Foot Massage Package, the Ozone Sterilization system is connected to the upper jets.

NuWhirl’s micrOzone generator targets tub plumbing where water can remain after baths, creating a higher concentration of ozone than many larger units. Its size—the smallest in the industry—means simple and flexible installation.
