The purification of water, from a well, a private community water system, or a municipal water system, is what we're about. We know water treatment and we know what works. We don't deal in fads, gimmicks, or supposed 'miracle' filters. At Metro Water Filter, we not only sell and install water filter systems, but we also service what we sell. We stand behind what we sell. Our products and services are backed by a satisfaction guarantee warranty.
