Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS people hear about when researching persistent, hard-to-remove contaminants in household water. It can enter sources through industrial uses and the breakdown of related fluorinated chemicals, and it tends to persist rather than break down quickly. Riverside Acres homeowners often first hear about PFUnA from utility notices, local reporting, or private testing. If you’re worried, focus on treatment approaches that are designed specifically to reduce PFAS.
Because PFUnA is usually found at very low concentrations, you won’t detect it by smell, taste, or sight in your tap water — which makes testing the only reliable way to know what’s present. PFAS like PFUnA act differently than familiar issues such as chlorine, sediment, or hard water, so typical cartridge filters may not be sufficient. For Riverside Acres homes—where mineral-rich, hard groundwater and occasional storm-influenced source changes are common—a whole-house strategy helps protect drinking, cooking, showering and everyday water use.
For whole-house PFUnA reduction, a granular activated carbon (GAC) filter is the most effective single-filter residential option. GAC media offers a very large surface area that adsorbs many organic contaminants, including a variety of PFAS. Effectiveness against PFUnA depends on using the right carbon type, allowing sufficient contact time, and maintaining appropriate flow rates — which is why a correctly sized whole-house carbon tank typically outperforms small, fast-flow cartridges.
At Mr. Pure Water we install whole-house GAC systems at the point where water enters Riverside Acres homes so treated water reaches every tap and appliance. We size systems to match household water use to avoid short contact times that reduce PFAS capture. Carbon media also needs routine maintenance and replacement as it becomes loaded to maintain consistent removal. If you have recent test results, we’ll use them to recommend the right whole-house GAC configuration for PFUnA reduction.
