Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS people ask about when researching persistent, hard-to-remove contaminants in household water. It can enter sources through industrial uses and the breakdown of related fluorinated compounds, and it tends to persist rather than break down quickly. Montverde homeowners often hear about PFUnA from utility advisories, local news, or private well testing; if it’s a concern for your family, the most practical next step is to look at treatment methods proven for PFAS reduction.
Because PFUnA usually occurs at very low concentrations, you won’t detect it by sight, smell, or taste — making testing the only reliable way to know what’s in your water. PFAS such as PFUnA behave differently from routine issues like chlorine taste, sediment, or the hard water minerals common in Lake County, so standard cartridge filters often aren’t enough. For Montverde homes, a whole-house solution can provide protection for drinking, cooking, showering, and all daily uses.
For whole-house reduction of PFUnA, a high-quality granular activated carbon (GAC) filter is generally the single most effective residential option. Carbon media offers extensive surface area that adsorbs many organic contaminants, including a range of PFAS. With PFUnA, performance relies on selecting the right carbon type, ensuring adequate contact time, and controlling flow rates — which is why a properly sized GAC tank typically outperforms small, fast-flow cartridges in Montverde homes.
Mr. Pure Water usually installs a whole-house GAC system at the point where water enters the home so treated water serves every tap and appliance — helpful in Montverde where hard, mineral-rich groundwater can also cause scale. We size systems to match household water use to avoid short contact times that reduce PFAS capture, and we recommend scheduled media maintenance and replacement to keep removal consistent as the carbon loads. If you have recent test results, bring them to our team and we’ll recommend the right GAC configuration for PFUnA reduction.
