Simple & Intuitive Water Care Using The Freshwater Salt Cartridge

The FreshWater Salt System sanitizes water by using a maintenance free, disposable cartridge. It will generate chlorine from the salt in the spa water. The cartridge lasts four months and can be easily replaced in seconds without tools or dealer assistance.

Simply set the desired chlorine output level with the touch of a button on the topside control. The system will automatically generate the appropriate amount of sanitizer, eliminating the guesswork of manual dosing.
