Kinetico HQ doesn't often respond to individual customers as there would be untold numbers of people calling and a staff would be needed to field such questions which often result in confusing details and one-sided complaints. So most are told to deal with the local dealer. I know it's not the best solution.
As I tried to mention before, no known arsenic contaminants are emitted from Kinetico carbon filters. This canbe a concern but I have never heard of this being a problem from Kinetico products. I will keep my ear to the rail.
You mentioned 'based on what (you) were reading..." but you haven't given reference. Can you provide a link to those details and why/how you believe your Kinetico RO is causing a problem? I have done a search and can find no indication.
CWS stands for Certified Water Specialist and that is through the Water Quality Association (WQA), not Kinetico.
