The culprit is residual chlorine which is injected into the municiple water to keep it biologically safe. Salt-based water softeners do not effect chlorine levels, they simply replace nutrient minerals with sodium or potassium chloride (salt). To find the most effective system to reduce chlorine levels, go to: www.wqa.org; Certifed products; go to NSF/ANSI-42; scroll to the system with the highest level of removal.
