The high salt content of the water, along with a very small amount of disinfectant, protects the chambers environment from harmful bacteria. Our Evolution filtration system completely recirculates the water a minimum of 3 times between each client (compared to swimming pool water, which is typically turned over once per day). The water passes through a 1 micron filter and is treated with ozone and UV light. In addition, clients are required to shower before and after their session. This ensures that the chamber is crystal clear and clean for every client, every time.
