Nature 2 Spa Mineral Purifier Single Cartridge

Nature2 Spa cartridge works with your existing filter to give you clean, clear water without high levels of chlorine. A difference you can see, feel, and smell.

Nature2 SPA works by automatically dissolving trace amounts of mineral elements into the water. Those elements act as a sanitizer to destroy bacteria and viruses. Just drop the Nature
2 SPA stick into the spa’s filter and forget about it for up to four months! Nature2 SPA will keep your spa sparkling clean and smelling great even in-between use. This is not a substitute for chlorine, it helps reduce the amount of chlorine needed to maintain your spa.
