PURITY SOURCE is the premier St. Louis dealer for PHSI's Point of Use Water Purification solution. We take ordinary tap water and through an extraordinary patented process turn it into pure, refreshing water.
Water Fountains, Bottled Water and Bottle-less Filter Coolers all share one common problem...they do not deliver pure water. Chemicals, Bacteria, Slime and other Contaminants can flow freely from these unprotected systems. PHSI's Water Guardian™ technology delivers a continuous supply of Fresh, Oxygenated, drinking water at the touch of a button. Glass after Pure Glass!
