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 household water. It can reach water sources through industrial uses and the breakdown of related fluorinated chemicals, and it tends to persist rather than break down quickly. Bertha homeowners often learn about PFUnA from utility notices, local reporting, or private well testing. If you’re worried, the most useful next step is to focus on treatment options specifically designed to reduce PFAS compounds.
PFUnA usually appears at very low concentrations, so you won’t detect it by sight, smell, or taste—making testing the only reliable way to know what’s in your tap water. PFAS like PFUnA behave differently than familiar issues in Bertha homes such as chlorine taste, sediment, or scale from hard, limestone-influenced groundwater, so simple cartridge filters often won’t be enough. A whole-house system offers practical protection for drinking, cooking and showering throughout the home.
For whole-house reduction of PFUnA, a high-quality granular activated carbon (GAC) tank is generally the best single-filter choice for residential systems. Granular carbon provides large surface area to adsorb many organic compounds, including a variety of PFAS. Effectiveness for PFUnA depends on using the right carbon type, allowing sufficient contact time, and controlling flow rates—factors that make a properly sized whole-house carbon tank more effective than a small, fast-flow cartridge in many Bertha homes with hard groundwater and scale concerns.
Mr. Pure Water usually installs whole-house GAC systems at the main water entry so treated water reaches every tap and appliance in Bertha houses. We size systems to match household water use to avoid short contact time that reduces PFAS capture, and we emphasize routine maintenance because carbon media must be replaced on schedule as it becomes loaded. If you have recent test results from your well or service line, we’ll use them to recommend the optimal GAC configuration for PFUnA reduction.
