Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS people ask about when researching persistent, hard-to-remove contaminants in drinking water. It can enter sources through industrial uses or the breakdown of related fluorinated chemicals, and it tends to resist quick breakdown. Koerber homeowners often hear about PFUnA from local reports, utility communications, or private testing; when that happens it’s helpful to consider treatment options designed specifically to reduce PFAS.
Because PFUnA usually occurs at very low concentrations, you’re unlikely to detect it by sight, smell, or taste in your tap water in Koerber. That makes testing the only reliable way to know what’s present. PFAS such as PFUnA behave differently than familiar issues like chlorine taste, sediment, or hard water, so simple cartridge filters often won’t be enough — a whole-house solution can protect drinking, cooking, showering, and everyday uses throughout your home.
For whole-house reduction of PFUnA, a quality granular activated carbon (GAC) filter is widely recommended as the most effective single-filter residential option. GAC media offers very large surface area that adsorbs many organic contaminants, including a range of PFAS. Effectiveness for PFUnA depends on using the right carbon type, allowing adequate contact time, and keeping appropriate flow rates — which is why a properly sized whole-house carbon tank typically performs better than a small, fast-flow cartridge.
At Mr. Pure Water we commonly install whole-house GAC systems at the main inlet so treated water reaches every tap in Koerber. We size systems to match household water use to avoid short contact times that can reduce PFAS adsorption. As with any adsorption media, carbon must be serviced and replaced on schedule to maintain removal performance as the media becomes loaded; if you have a recent water test, we’ll use it to recommend the right GAC configuration for PFUnA reduction.
