Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS people ask about when investigating stubborn, long-lasting contaminants in drinking water. It can reach water supplies via industrial uses or the breakdown of related fluorinated chemicals and does not break down quickly. Homeowners on Stacey Street often hear about PFUnA from utility notices, local reporting, or private testing, and if you’re worried it’s sensible to look at treatment approaches specifically aimed at reducing PFAS.
Because PFUnA is usually found at very low concentrations, it won’t give your water a noticeable smell, taste, or appearance — which makes testing the only reliable way to know what’s in your tap. PFAS behave differently than common complaints like chlorine, sediment, or hard water, so simple cartridge filters often won’t be sufficient. For Stacey Street homes, a whole-house strategy can be a practical way to lower exposure during 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) system. GAC media offers very large surface area that adsorbs many organic compounds, including a range of PFAS. With PFUnA, performance comes down to using the right carbon type, allowing enough contact time, and keeping appropriate flow rates — which is why a correctly sized whole-house carbon tank generally outperforms a small, fast-flow cartridge.
At Mr. Pure Water we typically deploy a whole-house GAC tank where water enters Stacey Street homes so every tap and appliance receives treated water. We size systems to match household demand to avoid short contact time that can reduce PFAS capture, and like all adsorption media, the carbon needs routine maintenance and scheduled replacement as it becomes loaded. If you have a recent water test, we’ll use it to recommend the right GAC configuration for PFUnA reduction in your home.
