"Good customer service!!!! I called them Christmas eve because our water softener gave up. Chris answered right away and walk me through so we can have our water back. Really appreciate the quick response and the work they’ve done. Very thorough and detailed explaining the issues we had and gave us tips on how to care for the new system they installed. Worked with us also paying for the whole system."

"Joe had provided me with a new RO system paired with a 3 stage whole house filter the system had a dramatic improvement to not only the quality of the drinking water but the Joe was straight to the point and fixed the problem I had the hardness of my water was also reduced and started seeing hard water spots on all of my fixtures the work was done flawlessly and clean would and have recommended to friends and family not just for the quality but he was at a fair price if your thinking about using Joe here’s your sign"

"You have to know going into this that their first price is not their final price. At the end we were saying could've we gotten a better price. If that type of negotiation bothers you don't call this company. What they sell is top notch, we are very happy with the water quality now."

"Set up appointment to observe issues with my water softener.  Employee from American Pure Water was very professional-showed me the issues and offered several options to purchase new or to repair old.  Showed me several options of new softeners with description of all shared with me . No pushy sales at all!!  Made decision  to purchase.  The following Saturday employee from American Pure Water arrived to install new water softener and hauled my old one away. Within forty five minutes I had a new softener installed and understood how all functions and what I need to do (if needed).   Throughout entire process employees were friendly, professional, not pushy, offered many options, seemed to have much knowledge and strong belief of their products. On time for both appointments-no waiting around.  Highly recommend American Pure Water to anyone searching or just wanting information on water softeners, drinking water systems, air purification, needed salt delivery, or in need of iron &/or sulfur removal.  As they state, "We have what you are looking for!"
