Product Overview
The SunPurity™ Mineral Purifier (part #6890‑780) is a genuine OEM mineral cartridge designed for Sundance® spas. It uses a blend of natural minerals to help sanitize spa water alongside your regular chlorine or bromine routine, reducing how much chemical sanitizer you need to keep the water clear and balanced.
The cartridge installs directly into your spa’s filter compartment—if your spa has a weir gate chamber designed for mineral cartridges, that’s the ideal placement; otherwise, positioning it near the filters so it stays exposed to circulating water works just as well. It should not be placed where it could obstruct jets or water intake valves, since it needs steady water flow across it to work effectively.
Each SunPurity™ cartridge lasts up to four months under normal use, after which its mineral content is depleted and a fresh cartridge is needed to keep getting the reduced‑chemical benefit. While it’s in place, continue testing your spa water weekly to keep sanitizer levels properly balanced—the mineral cartridge supplements your regular sanitizing routine rather than replacing water testing altogether. Because #6890‑780 is manufactured to Sundance®’s own OEM specifications, it’s sized and formulated specifically for Sundance® spas, restoring the same mineral‑assisted water treatment these spas were designed to use.
