Hot Spring Freshwater Salt System Refill

This system is specifically engineered for use with Hot Spring Highlife® and Limelight® collection spa models. It will not function correctly with other spa brands or older models not equipped for this system.

Each cartridge is designed to last up to four months, meaning this three-pack provides a full year of water care. Actual longevity can vary slightly depending on your spa usage and water conditions.

While this system automates chlorine generation and significantly reduces the need for manual chemical additions, you will still need to occasionally balance your water's pH and alkalinity. It is a sanitizer system, not a complete replacement for all water chemistry maintenance.

Yes, many users notice that water treated with this salt system feels softer and smoother on the skin compared to traditional chlorine methods. It also helps eliminate the harsh chemical odors often associated with standard sanitizers.

The system is designed for a straightforward, plumbed-in installation within compatible spas. Because it is a proprietary system for specific Hot Spring models, the process is streamlined, but you should refer to your owner's manual for specific steps to ensure proper seating and activation.
