Including filter system and high-performance PFUnA filter.
PFUnA is a member of the PFAS family that people research when learning about persistent, hard-to-remove contaminants in drinking water. 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. Jarrett homeowners often hear about PFUnA from a utility advisory, local reporting, or private well testing; when that happens it’s sensible to consider treatment options designed specifically to reduce PFAS.
Because PFUnA usually occurs at very low concentrations, you generally won’t detect it by sight, smell, or taste in your tap water. That makes testing the only reliable way to know what’s present. PFAS such as PFUnA behave differently from familiar issues like chlorine taste, sediment, or hard water, so standard cartridge filters may not provide adequate protection. For many Jarrett households, a whole-house system is a practical way to limit exposure during drinking, cooking, showering, and daily use.
For whole-house reduction of PFUnA, a high-quality granular activated carbon (GAC) filter is the most effective single-filter residential choice. Carbon media offers a very large surface area that adsorbs many organic compounds, including a range of PFAS. Performance against PFUnA depends on choosing the correct carbon type, allowing sufficient contact time, and controlling flow rates—so a properly sized whole-house carbon tank is typically more effective than a small, fast-flow cartridge in a Jarrett home.
At Mr. Pure Water we install whole-house GAC systems at the main water entry so treated water serves every tap and appliance in your Jarrett home. We size systems to match household usage to avoid short contact times that reduce PFAS capture. Like all adsorption media, carbon requires scheduled maintenance and replacement as it becomes loaded to maintain removal performance. If you have recent test results, we’ll use them to recommend the right GAC configuration for PFUnA reduction in your house.
