Including filter system and high-performance PFUnA filter.
PFUnA is one member of the PFAS family that homeowners hear about when researching persistent, hard-to-remove contaminants in drinking water. It can reach water supplies through industrial uses and the breakdown of related fluorinated chemicals, and it tends to remain rather than break down quickly. People in Lafayette often discover concerns about PFUnA from utility notices, local reporting, or private testing of a well or municipal supply; if you’re worried, the most useful next step is to look at treatment options designed specifically to reduce PFAS.
Because PFUnA is usually found at very low concentrations, it won’t change the smell, taste, or appearance of your water — which makes testing the only reliable way to know what’s present in Lafayette homes. PFAS chemicals like PFUnA act differently than familiar issues such as chlorine, sediment, or mineral hardness, so simple cartridge filters or softeners often won’t address them. For many residents, a whole-house strategy is a practical option to reduce exposure when drinking, cooking, showering, and using appliances.
For whole-house reduction of PFUnA, the most effective single-filter choice in residential systems is a high-quality granular activated carbon (GAC) tank. Carbon media provides extensive surface area to adsorb many organic contaminants, including a range of PFAS compounds. Effectiveness for PFUnA depends on using the right carbon type, allowing adequate contact time, and maintaining appropriate flow rates — so a properly sized GAC tank serving a Lafayette home will perform better than a small, fast-flow cartridge.
Mr. Pure Water installs whole-house GAC systems at the main water entry to Lafayette homes so filtered water reaches every tap and appliance. We size systems to match household water use and avoid short contact times that reduce PFAS adsorption. Like all adsorption media, carbon needs regular maintenance and scheduled replacement as it becomes loaded, and if you have a recent water test we’ll use it to recommend the right GAC configuration for PFUnA reduction.
