Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS chemicals people ask about when researching persistent, hard-to-remove contaminants in drinking water. It can reach water supplies through industrial use and the breakdown of related fluorinated compounds, and it tends to remain rather than break down quickly. Lois homeowners often hear about PFUnA from local news, utility notices, or private well testing; if it’s a concern for your household, focusing on treatment approaches made to reduce PFAS is a sensible next step.
Because PFUnA is usually found at very low concentrations, you’re unlikely to detect it by sight, smell, or taste — which makes testing the only reliable way to know what’s coming from your tap. PFAS like PFUnA act differently than familiar problems such as chlorine taste, sediment, or Florida’s common hard water, so simple point-of-use cartridge filters often aren’t sufficient. For Lois homes, a whole-house solution can help limit exposure during drinking, cooking, showering, and everyday chores.
For whole-house reduction of PFUnA, a high-quality granular activated carbon (GAC) filter is generally the single most effective residential option. Carbon media provides a very large surface area that can adsorb many organic compounds, including various PFAS. With PFUnA, how well the system works depends on using the appropriate carbon type, ensuring enough contact time, and controlling flow rates — which is why a correctly sized whole-house carbon tank matters more than a small, fast-flow cartridge.
Mr. Pure Water typically treats PFUnA in Lois with a whole-house GAC system placed at the main water entry so every tap and appliance gets treated water. We size systems to match household water use to avoid short contact times that reduce PFAS capture, and like all adsorption media, carbon must be serviced and replaced on schedule as it becomes loaded. If you have recent test results for your Lois water, we can tailor the system configuration to best address PFUnA reduction.
