SunPurity provides a high level of water purification for your spa. Made by Nature 2 for Sundance Spas.
Sundance Spas SunPurity Mineral Cartridge leaves water clean, clear, and soft. An alternative to chlorine when used in combination with MPS (monopersulfate), the SunPurity cartridge fits into the bromine dispenser of the filter bays of 880 and 780 Series hot tubs. It reduces the potential for unpleasant odors and residue lines, and can be used with your hot tub ozone system.
Lasts up to four months. Not available in Canada or Europe.
Note: The SunPurity requires only a small maintenance dose of non-chlorine oxidizer and should not be mixed with bromine and bromides. The SunPurity cartridge is not compatible with biguanides such as SoftSoak or Baqua.
