Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS chemicals homeowners hear about when researching persistent, hard-to-remove contaminants in drinking water. It can get into water supplies through industrial uses and the breakdown of related fluorinated compounds, and it tends to remain rather than break down quickly. In Madison, homeowners often discover PFUnA concerns after utility communications, news coverage, or private well testing; if you’re worried, the best step is to consider treatment options designed specifically to lower PFAS in household water.
Because PFUnA is generally found at very low concentrations, it won’t give off a smell, taste, or visible sign in your tap water — which makes testing the reliable way to know what’s present. PFAS like PFUnA behave differently than common local issues such as chlorine taste or mineral hardness, so simple cartridge filters or softeners aren’t usually enough. For Madison families who want protection at every faucet and shower, a whole-house strategy is often the more practical choice.
For whole-house reduction of PFUnA, the most effective single-filter option in a residential setting is a high-quality granular activated carbon (GAC) system. Carbon media offers a very large surface area that adsorbs many organic compounds, including a variety of PFAS. Performance against PFUnA depends on using the right carbon type, providing enough contact time, and controlling flow rates — which is why a correctly sized whole-house carbon tank matters more than a small, fast-flow cartridge filter.
At Mr. Pure Water we typically install whole-house GAC systems at the point where water enters Madison homes so treated water reaches every tap and appliance. Systems are chosen based on household water use to prevent short contact times that reduce PFAS capture. Like any adsorption media, carbon must be maintained and replaced on schedule as it becomes loaded; if you have a recent water test from your Madison home, we can use it to recommend the right GAC configuration for PFUnA reduction.
