Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS compounds people look for when investigating persistent contaminants in drinking water. It can reach groundwater via industrial uses and from the breakdown of related fluorinated chemicals, and it tends to persist rather than break down quickly. Three Lakes homeowners often hear about PFUnA from local water reports, utility notices, or private testing of well water drawn from the Floridan aquifer. If it’s a concern for your household, focusing on treatment methods designed for PFAS reduction is the practical next step.
Because PFUnA usually appears at very low concentrations, you won’t detect it by smell, taste, or sight — even in Three Lakes homes that use hard groundwater. That makes testing the only reliable way to know what’s coming from your tap. PFAS like PFUnA behave differently from familiar issues such as chlorine taste, sediment, or mineral hardness, so standard cartridge filters or softeners may not address it. For many families in Osceola County, a whole-house solution is a sensible way to reduce exposure during drinking, cooking, and showering.
For whole-house reduction of PFUnA, a high-quality granular activated carbon (GAC) filter is the most effective single-filter option commonly used in residences. GAC media offers a very large surface area that adsorbs many organic contaminants, including several PFAS compounds. Effective PFUnA removal depends on using the right carbon type, allowing sufficient contact time, and keeping flow rates within the design range — which is why a correctly sized whole-house carbon tank outperforms small, high-flow cartridges.
At Mr. Pure Water we typically install a whole-house GAC system at the point where municipal or well water enters Three Lakes homes so every tap and appliance is treated. We size systems to match household water use to avoid short contact times that can reduce PFAS capture, and we schedule media maintenance since carbon’s adsorption capacity is finite. If you have recent test results from your Floridan aquifer well or city supply, bring them to us and we’ll recommend the right GAC configuration for PFUnA reduction.
