Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS people ask about when researching persistent, hard-to-remove drinking-water contaminants. It can reach water supplies through industrial uses and the breakdown of related fluorinated chemicals, and it tends to persist rather than break down quickly. Local homeowners in Runnymede often first hear about PFUnA from utility notices, media reports, or private well testing—especially in a humid subtropical area where private wells and municipal mixes vary. If PFUnA is a concern for your household, it’s sensible to consider treatment options that target PFAS specifically.
Because PFUnA usually occurs at very low concentrations, you won’t detect it by sight, smell, or taste, which makes testing the only reliable way to know if it’s present. PFAS like PFUnA behave differently than familiar water issues such as chlorine taste, sediment, or mineral scale, so standard cartridge filters often fall short. For Runnymede homes—where mineral scale and other well-water contaminants can also be factors—a whole-house system can help reduce exposure from drinking, cooking, showering, and everyday use.
For whole-house reduction of PFUnA, the most effective single-filter residential option is a high-quality granular activated carbon (GAC) tank. GAC media offers large surface area that adsorbs many organic compounds, including a range of PFAS, and PFUnA removal hinges on using the right carbon type, adequate contact time, and appropriate flow rates. That’s why a properly sized whole-house carbon tank—rather than a small, fast-flow cartridge—matters for consistent PFUnA capture in a household system.
At Mr. Pure Water, we commonly address PFUnA in Runnymede with a whole-house GAC system installed at the main water entry so every tap and appliance receives treated water. We size systems to match household water use and avoid the short contact times that reduce PFAS adsorption, and we emphasize regular maintenance and media replacement because carbon becomes loaded over time. If you have recent water test results, bring them in and we’ll recommend the appropriate whole-house carbon configuration for PFUnA reduction.
