Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS chemicals homeowners hear about when researching persistent, hard-to-treat contaminants in drinking water. It can make its way into water supplies from industrial uses and from the breakdown of related fluorinated compounds, and it tends to remain rather than break down quickly. In Scanlon, residents often discover concerns about PFUnA after utility updates, local reporting, or private testing. If you’re worried, the most useful next step is to consider treatment methods designed specifically to reduce PFAS.
Because PFUnA is usually found at very low concentrations, you won’t detect it by sight, smell, or taste — which is why testing matters for Scanlon homes. PFAS like PFUnA behave differently from familiar issues such as chlorine taste, sediment, or hard water, so a basic pitcher or cartridge filter may not be sufficient. A whole-house strategy helps protect drinking, cooking, bathing, and other everyday uses throughout your home.
For whole-house reduction of PFUnA, the most effective single-filter choice for many residential systems is a high-quality granular activated carbon (GAC) tank. Carbon offers a very large surface area that can adsorb a variety of organic contaminants, including PFAS compounds. When treating PFUnA, results depend on using the appropriate carbon type, allowing enough contact time, and keeping flow rates within the tank’s design limits — so a correctly sized whole-house carbon system can outperform a small, fast-flow cartridge.
At Mr. Pure Water we typically install a whole-house GAC system at the point where water enters Scanlon homes so treated water is available at every tap and appliance. We size systems based on household water use to avoid short contact times that reduce PFAS capture, and we emphasize scheduled maintenance because carbon media loses effectiveness as it becomes loaded. If you have recent water test results, we’ll use them to recommend the best whole-house carbon configuration for PFUnA reduction.
