Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS compounds homeowners hear about when researching persistent contaminants that are hard to remove from drinking water. It can reach water supplies through industrial uses and the breakdown of related fluorinated chemicals, and it tends to persist rather than break down quickly. Residents in Lewis may first learn about PFUnA from a utility notice, local news, or a private well test; when that happens, it’s best to consider treatments specifically designed to reduce PFAS compounds.
Because PFUnA usually occurs at very low levels, you typically won’t be able to see, smell, or taste it in your tap water in Lewis. That makes testing important if you want to know what’s actually in your supply. PFAS like PFUnA act differently than familiar issues such as chlorine taste, sediment, or hard water, so standard cartridge filters often aren’t sufficient. A whole-house system is a practical option to limit exposure during drinking, cooking, bathing, and everyday household use.
For whole-house reduction of PFUnA, the most effective single-filter choice in many residential systems is a high-quality granular activated carbon (GAC) tank. Carbon media offers a very large surface area that adsorbs a variety of organic compounds, including many PFAS. Effectiveness for PFUnA depends on using the appropriate carbon type, allowing sufficient contact time, and controlling flow rates—so a correctly sized whole-house carbon tank usually outperforms small, fast-flow cartridges.
At Mr. Pure Water we install whole-house GAC systems at the main service entry so every faucet and appliance in your Lewis home receives treated water. We size systems to match household water use to prevent short contact times that can reduce PFAS capture. Like all adsorption systems, the carbon media requires regular maintenance and periodic replacement to maintain performance; if you have recent test results, we’ll use them to recommend the best GAC configuration for PFUnA reduction.
