Our first goal at WATER ZONE is to offer you as many "natural" solutions to water problems as possible - solutions without salt or chemicals doing the work. Inside our site you will find our catalytic water conditioners that does not remove calcium and magnesium but stops these minerals from binding and causing (the true hard water minerals) build up problems in your water system - then we go to filtration. You will also find our filtration systems that can naturally filter out rust causing iron molecules, remove chlorine where needed and the rotten egg smell caused by hydrogen sulfide. Our KDF filter systems also remove or greatly decrease pesticides that we often get from run-off from in agriclultural areas and heavy metals. Make sure you check out our complete systems with catalytic conditioners mated with our fine filters. We also offer replacement filters where needed and special drinking water systems to get "better than bottled quality" water right at you own sink. We also offer salt softener units for those that simply MUST have a non-environmentally safe unit we do offer salt systems but ours are top quality units that will use less salt and work more efficiently than others. And finally, we offer our top of the line system, which is a totally maintanance free system which, once set up will require nothing for 5 - 7 years and we guarantee that. If you have any questions feel free to call us at 269-468-6800 or toll free at 888-468-0680 or e-mail at waterzonesoft@aol.com - If we are out just leave a message and when to call and we are glad to call you back!
