Simple & Intuitive
Water Care

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

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

Longer Lasting,
Natural Feeling Water

The FreshWater Salt System uses fewer chemicals than traditional water care, reducing harsh odors for softer-feeling water that is gentler on eyes and skin.

With fewer additives needed, the water can stay clean and fresh for up to a full year* before needing to be drained and refilled. This conserves water, saves money and reduces time previously spent on complicated water care.

Pair the salt system with an anti-microbial Silver Ion Sanitizer for the ultimate fresh water experience.

An Easier Way To Hot Tub

The FreshWater Salt System leaves water clean and ready to use, so you can spend more time enjoying your spa and less time maintaining it.

The system was designed to help keep water clean and fresh for a full year, up to 3x longer than other systems, saving you time and money with fewer drains and refills.

*Factors such as bather load and water chemistry can impact water life. When the spa is properly maintained, a 3-pack of cartridges with the FreshWater® Salt System will keep water clean and fresh for a full year. Product availability depends on your region. Please check with your local dealer.
