Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS chemicals homeowners hear about when investigating long-lasting, difficult-to-remove contaminants in drinking water. It can reach water supplies through industrial uses and from the breakdown of related fluorinated compounds, and it tends to persist rather than break down quickly. Many Wallace residents first learn about PFUnA from a utility notice, local reporting, or private testing. If you’re concerned, the most useful step is looking at treatment options designed specifically to lower PFAS in household water.
Because PFUnA is usually present at very low concentrations, you’re unlikely to detect it by sight, smell, or taste in your tap water — which is why testing matters. PFAS like PFUnA behave differently than familiar issues such as chlorine taste, sediment, or hard water, so typical cartridge filters often won’t address them adequately. For Wallace homeowners who want protection at every fixture, a whole-house strategy can reduce exposure from drinking, cooking, showering, and routine water use.
For whole-house reduction of PFUnA, the most effective single-filter choice in residential systems is a granular activated carbon (GAC) tank. Carbon media offers a very large surface area that can adsorb many organic contaminants, including certain PFAS. Performance against PFUnA depends on using the appropriate carbon type, allowing adequate contact time, and keeping flow rates within design limits — which is why a correctly sized whole-house carbon tank outperforms small, fast-flow cartridges for this application.
At Mr. Pure Water we install whole-house GAC systems at the point where water enters Wallace homes so every tap and appliance receives treated water. Systems are sized to match household water use to avoid short contact times that can reduce PFAS removal. As with all adsorption media, carbon requires regular maintenance and periodic replacement to remain effective as it becomes loaded. If you have a recent water test from your Wallace property, we’ll use it to recommend the right GAC configuration for PFUnA reduction.
