How Does Nature² Work? The Purifier accurately controls the water flow through replaceable cartridges. A non-electrical reaction 'activates' oxygen to kill bacteria, algae, and viruses. Nature² releases trace amounts of natural, algaestatic and bactericidal minerals into the pool to help prevent bacteria and algae growth.   How Do I Know If Nature² Is Working? The most reliable test of effectiveness is the improved quality of water. You'll notice a remarkable difference. Visual clarity and sparkle, even at extremely low levels of residual oxidizer, indicate that theNature² Purifier is working properly.   Is Nature² A Filter? No. A filter is designed to remove large particles and debris, while Nature² disinfects pool water by killing 99.96% of bacteria, algae and viruses, which are too small to be caught by a filter. So you need both a filter and Nature².   Is Nature² An 'Ionizer'? No. Ionizers require electricity to discharge copper (or metal alloy) ions into pool water. Conversely, Nature²'s non-electrical ceramic & mineral cartridge converts oxygen to sanitizer, in addition to releasing micro-doses of bactericide and algaestat to keep a pool sanitary. What Makes Nature² The #1 Chlorine Alternative? The #1 Chlorine Alternative according to an independent pool industry survey Installed in over 100,000 pools in the USA The only alternative sanitizer manufacturer who earned the Good Housekeeping Seal on all products Carried by more than 3,000 pool dealers nationwide and growing Using breakthrough technology protected by 17 worldwide patents and 20 patents pending Water so pure, it's even lower in bacteria than government standards for drinking water.
