Including filter system and high-performance PFUnA filter.
PFUnA is one of the longer-lasting PFAS that homeowners hear about when investigating persistent contaminants in drinking water. It can get into water supplies through industrial uses or the breakdown of related fluorinated chemicals, and it does not break down quickly. Gretna residents often discover PFUnA after a utility notice, news coverage, or a private well test; if you have concerns, it’s sensible to consider treatment methods designed specifically to reduce PFAS.
Because PFUnA is usually present at trace levels, you’re unlikely to detect it by sight, smell, or taste in Gretna’s tap water. That invisibility makes testing the only reliable way to know what’s coming from your pipes. PFAS like PFUnA behave differently than common issues such as chlorine, sediment, or hard water, so typical point-of-use cartridges or basic filters may not address it. For many Gretna households, a whole-house solution is a practical option to lower exposure during drinking, cooking, and showering.
For whole-home reduction of PFUnA, a granular activated carbon (GAC) tank is the most effective single-filter residential option. GAC media offers a very large surface area that adsorbs a variety of organic contaminants, including many PFAS. With PFUnA, results hinge on selecting the right carbon type, ensuring adequate contact time, and maintaining appropriate flow rates—so a properly sized whole-house carbon system can perform much better than a small, fast-flow cartridge in Gretna homes.
At Mr. Pure Water we install whole-house GAC systems at the main service entry so treated water serves every faucet and appliance in your Gretna home. Systems are chosen based on household water use to avoid short contact times that reduce PFAS capture. Like all adsorption media, the carbon bed requires regular maintenance and replacement as it becomes loaded. If you have recent test results, bring them to us and we’ll recommend the appropriate GAC configuration to help reduce PFUnA.
