How-To Guides | Alternative Sanitizers - Odor-free Options for your Spa

If you're happy using a conventional spa sanitizer such as bromine, we won't suggest a change. But if you're looking for an odor-free, yet highly effective alternative spa purification system, Nature2 or Frog may be perfect for you. Going chlorine or bromine free has never been easier!

Nature2 Spa Purifier

Nature 2 water purification technology for spas gives the purest, clearest water imaginable, with virtually no odor. It works using a silver catalyst to kill microbes. Since it lasts 4 months, you just replace it with each water change.

Keep your hot tub water sparkling clean using fewer harsh chemicals. That makes it easier to keep water pH in the proper range, which not only feels better, but your equipment will last longer. No more red, burning eyes, irritated skin, or discolored hair. Let Nature 2 sanitize your spa automatically.

Installation

The Nature2 spa purifier installs in seconds inside your hot tub's filter cartridge.  It works on both pressure and suction type filtration systems and is suitable for spas up to 500 gallons.  Your spa should be circulated a minimum of 4 hours daily to be effective.

NOTE:Your filter cartridge must be at least 8" long, and have an opening diameter of at least 1 1/4" to accept the Nature2 purifier cartridge.
