Including filter system and high-performance PFUnA filter.
PFUnA is one member of the PFAS family that homeowners sometimes find when investigating persistent, hard-to-remove contaminants in drinking water. It can reach water supplies through industrial uses and from the breakdown of related fluorinated chemicals, and it tends to persist rather than break down quickly. In Red Head, local residents often first hear about PFUnA from utility communications, news coverage, or private lab tests. If you’re worried, the most useful step is to look at treatment methods that specifically target PFAS compounds.
Because PFUnA usually exists at very low concentrations, you won’t detect it by sight, smell, or taste in tap water—so testing is the only reliable way to know if it’s present. PFAS like PFUnA act differently than common household water issues such as chlorine taste, sediment, or hard water, and standard cartridge filters often won’t remove them effectively. For many Red Head homes, a whole-house strategy is a sensible way to reduce exposure from drinking, cooking, bathing, and other everyday uses.
For whole-house reduction of PFUnA, residential systems most often rely on a high-quality granular activated carbon (GAC) filter as the single most effective cartridge-free option. GAC media provides a very large surface area that adsorbs many organic contaminants, including various PFAS. With PFUnA, results depend on using the proper carbon type, ensuring enough contact time, and maintaining appropriate flow rates—so a correctly sized whole-house carbon tank typically performs better than a small, fast-flowing filter cartridge.
At Mr. Pure Water we usually address PFUnA in Red Head homes with a whole-house GAC system installed at the main water entry so every tap and appliance receives treated water. Systems are chosen to match household water use to avoid short contact times that can reduce PFAS removal. Like all adsorption media, carbon needs regular maintenance and periodic replacement as it becomes saturated. If you have recent test results from your Red Head property, we can tailor the system size and configuration to improve PFUnA reduction.
