*Please be advised that counterfeit Freshwater Salt Cartridges exist and are being sold on sites, such as Amazon.

You can be sure you have an authentic Freshwater Salt Cartridge in several ways: 

  • Always buy your FreshWater Salt System Cartridge from an authorized Hot Spring or Caldera Spas dealer. 
  • Authentic Freshwater Salt System Cartridges will have gray pins (a fake may have a white pin) 
  • Counterfeit cartridges may also display bubbling in the strips.
