Stephen Houpis was extremely helpful when we were choosing our reverse-osmosis water filter. He provided several suitable options, and once we made our decision, he did an impeccable job of installing the filter. Once installed, we could tell that the filter was doing the job as advertised. Our water now tastes clean and pure, and our minds are at ease knowing that we are avoiding the contaminants and residues frequently found in city water. Furthermore, Stephen has contacted us several times to make sure the filter is working properly and that we are satisfied with it. We highly recommend Stephen to anyone looking for a high-quality water filter system for their home.
