Nature2 Replacement Cartridges. For optimal performance, make replacements every six months.

Using time-released levels of silver and copper crystals, the Mineral Cartridge disinfects the water, killing an array of microorganisms. The SmartPure® Mineral Cartridge acts as a biostat as well. It keeps the growth of algae and bacteria in check – without regular additions of algaecide and other specialty treatments. By helping maintain pH levels, the SmartPure® Mineral Cartridge also makes the pool water pleasant on swimmers' skin. The industry's top-rated Mineral Cartridge fits into ALL Blue Haven SmartFilters® and is powered by pool-water flow. Direct placement in the filter – through which all water passes – helps ensure a healthy swimming environment even in hot weather and heavily used pools.
