Including filter system and high-performance PFUnA filter.
PFUnA is one member of the broader PFAS family that homeowners hear about when investigating persistent, difficult-to-treat contaminants in drinking water. It can reach water supplies through industrial uses or the gradual breakdown of related fluorinated chemicals, and it tends to remain rather than disappear quickly. Residents of Old Town often become aware of PFUnA after reading a notice, seeing local coverage, or receiving results from a private test. If you’re worried, focus on treatment options that are designed specifically to reduce PFAS.
Because PFUnA is usually present at very low levels, it won’t have a noticeable smell, taste, or appearance—so you can’t reliably detect it by sampling water at the tap. PFAS such as PFUnA also act differently from common complaints like chlorine, sediment, or hard minerals, meaning standard point-of-use cartridge filters often won’t be sufficient. For many Old Town homeowners, a whole-house system is a sensible way to lower exposure during drinking, cooking, showering, and everyday use.
When the goal is whole-house reduction of PFUnA, a granular activated carbon (GAC) filter is typically the most effective single-filter choice for residential installations. GAC media offers extensive surface area that adsorbs many organic compounds, including various PFAS. Effectiveness against PFUnA depends on using the appropriate carbon type, allowing enough contact time, and controlling flow rates—so a correctly sized whole-house carbon tank usually outperforms a small, quick-flow cartridge.
At Mr. Pure Water we commonly address PFUnA in Old Town homes with a whole-house GAC system installed at the main water inlet so every tap and appliance receives treated water. Systems are sized around household water use to avoid short contact times that reduce PFAS capture, and the carbon media requires routine maintenance and timely replacement as it becomes loaded. If you have a recent water test from your Old Town property, we can tailor the system configuration to target PFUnA most effectively.
