Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS people ask about when they’re learning how persistent contaminants behave in drinking water. It can get into water supplies through industrial uses and from the breakdown of related fluorinated chemicals, and it tends to stay in the environment rather than break down quickly. McDavid homeowners usually hear about PFUnA after a utility advisory, local reporting, or a private test; if it’s on your mind, the smartest first step is to consider treatment options that specifically target PFAS.
Because PFUnA is often present at very low levels, you won’t detect it by sight, smell, or taste — which makes testing the only reliable way to know what’s in your tap water in McDavid. PFAS such as PFUnA act differently than familiar issues like chlorine taste, sediment, or mineral hardness, so simple point-of-use cartridge filters may not provide adequate protection. For many families, a whole-house strategy is a sensible choice to lower exposure during drinking, cooking, bathing, and everyday use.
For whole-home reduction of PFUnA, the single most effective residential filter choice is a granular activated carbon (GAC) system. GAC media offers extensive surface area that can adsorb a variety of organic contaminants, including many PFAS. Effective removal of PFUnA depends on using the appropriate carbon type, allowing enough contact time, and maintaining suitable flow rates — which is why a correctly sized whole-house carbon tank matters more than a small, fast-flowing cartridge in a McDavid residence.
At Mr. Pure Water we typically address PFUnA with a whole-house GAC system placed at the point where water enters the home so every tap and appliance benefits. Systems are sized around household water use to prevent overly fast flow that can reduce PFAS capture. Like any adsorption media, carbon needs routine maintenance and periodic replacement as it becomes loaded to maintain performance. If you have recent test results from McDavid, we’ll use them to recommend the right GAC configuration for reducing PFUnA in your home.
