Haferman Water Conditioning, Inc./ Kinetico offers professional, prompt service along with robust products designed to last longer than most system products sold commercially today. They just came out and fixed our Reverse Osmosis Water System and then installed a chlorine filter for the household water that same visit. We have been using their system for three years and have found it far superior to anything else on the market today. I think their pricing is fair considering what I'm getting in return. While other water softeners last about ten years, Haferman systems have a thirty year life expectancy, making them the best value around. The benefits of the quality products they offer far exceed their competitors and really puts them in a league of their own. If you want the best products and the best value then I strongly suggest trying this company. Nothing else out there even comes close!
