LOL, just click on my website, we sell only the best, the proof is in the thousands of units we put out every month. blah blah blah... lol. Fact is, we manufacture alternative water conditioning systems and components, but we are far more honest than most of the companies out there selling snake oil. We are very up front and honest about alternatives to traditional salt water softening. We also make no claims as to a systems effectiveness, we let the companies who we supply make the claims. We also do extensive in-house testing and some of the results are surprising, but scientifically the tests are not able to be consistently repeated and therefore we will continue to test until we can consistently prove our findings before we make any claims. I also work directly with a couple of cooling tower and boiler chemical companies and we field test many different designs utilizing a simple scale/corrosion test method. We do this on multiple cooling tower and boiler systems so that the results should be easily determined, this again has proven difficult except for more traditional water treatment methods. Using catalytic module, magnetic modules, Frequency generators, anti-scale medias, etc, the results are mixed, inconclusive, and sometime surprisingly good. more traditional treatment methods ie: softening, RO, DI, polyphosphate injection, etc all work exactly as expected, no surprises and the results are easily repeatable. I will finish on this note, if a water treatment device makes a true change in the water, a test kit of some sort would be able to be made to prove the effectiveness, without a test method to determine the continued effectiveness of the treatment process, not testimonial, opinions, flawed or biased studies (paid for studies, grants, etc.) then the method requires a much more stringent and scientific approach.
All that being said, I find these technologies exciting and interesting. Salt water softening is not always needed or desired. Many people do not like the feel of softened water, and many people have water reuse requirements that are not exactly compatible with water softening. Brine restrictions, while often completely unnecessary, are sometime needed and alternatives are desired. Many people simply can no longer handle the salt bags due to physical limitations and alternatives to softening are an obvious solution. We assemble equipment for many soft water alternative companies and we manufacture many ourselves.
As for me, I will definitely stick with my traditional salt based softener. I have also surveyed over 500 installers/dealers last year during training seminars, and I have only had a couple of people say that they do not have a softener in their own home. They sell alternatives, but for their own use, true softening still remains the best solution for the best quality water.
