The company i purchased through was amazing, I hopped on here to say that the quality of the system is great. I am very pleased, we have had our water tested again professionally from an independent third party lab and the results actually shocked me. Most systems say they will REDUCE contaminants. the hydronex removed almost all contaminants (i say almost because there is no system out there that as the ability to fully remove chlorine. but the hydronex removes 99%! ) User's recommendation: Puronics is AMAZING. Make sure you go go though a great authorized dealer.
