Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS chemicals homeowners ask about when researching persistent, difficult-to-remove contaminants in drinking water. It can get into water through industrial uses and from related fluorinated compounds breaking down, and it tends to persist rather than break down quickly. In Chapel Hill many residents first hear about PFUnA from news stories, test results, or notices, and the sensible next step is to look at treatment options specifically aimed at reducing PFAS.
Because PFUnA is usually found at very low levels, you generally won’t notice it by sight, smell, or taste — which makes testing important if you’re worried about what’s coming from the tap. PFAS like PFUnA act differently than familiar issues such as chlorine taste, sediment, or hard water, so standard cartridge filters often aren’t enough. For Chapel Hill homes, a whole-house plan helps reduce exposure during drinking, cooking, showering, and everyday household use.
For whole-house reduction of PFUnA, a granular activated carbon (GAC) filter is the most commonly recommended single-filter solution for residential systems. GAC media provides a very large surface area that can adsorb many organic contaminants, including various PFAS. Effectiveness against PFUnA depends on using the right carbon type, allowing adequate contact time, and maintaining appropriate flow rates — which is why a properly sized whole-house carbon tank matters more than a small, fast-throughput cartridge.
At Mr. Pure Water we install whole-house GAC systems at the point where water enters Chapel Hill homes so every tap and appliance gets treated water. We size systems to match household water use to avoid short contact times that reduce PFUnA capture, and we emphasize regular maintenance because carbon media needs replacement as it becomes loaded. If you have recent test results, bring them in and we’ll recommend the right whole-house configuration for reducing PFUnA in your home.
