Including filter system and high-performance PFUnA filter.
PFUnA is one member of the broader PFAS family that homeowners ask about when researching persistent contaminants in drinking water. It can enter water through industrial uses or the breakdown of related fluorinated compounds and does not break down quickly, so it can be difficult to remove with basic treatment. Residents of Gaskins Still often hear about PFUnA after reading local coverage, a utility advisory, or from private well testing; if you’re worried, the most useful next step is to concentrate on treatment options designed specifically to reduce PFAS.
Because PFUnA is usually found at low concentrations, you won’t detect it by sight, smell, or taste, which makes testing the only reliable way to know what’s in your tap water. PFAS such as PFUnA behave differently from common issues like chlorine taste, sediment, or hard water, and standard cartridge filters aren’t always sufficient. For many Gaskins Still homes, a whole-house system is a sensible way to lower exposure from drinking, cooking, bathing, and everyday household use.
For whole-house reduction of PFUnA, the most effective single-filter residential option is a properly designed granular activated carbon (GAC) system. GAC uses a very large surface area to adsorb a variety of organic compounds, including many PFAS. Real-world performance for PFUnA depends on selecting the right carbon type, allowing adequate contact time, and maintaining appropriate flow rates—factors a correctly sized whole-house carbon tank addresses better than a small, fast-flow cartridge.
At Mr. Pure Water we typically install a whole-house GAC tank at the main service entry so treated water reaches every tap in your Gaskins Still home. We size the system around your household water use to avoid short contact time that can reduce PFAS capture, and we recommend routine maintenance because carbon media becomes loaded and needs replacement on schedule. If you have recent water test results from your property, bring them to us and we’ll recommend the right GAC configuration for PFUnA reduction.
