Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS people research when they’re concerned about persistent contaminants in their water. It can get into water supplies through industrial uses and from the breakdown of related fluorinated compounds, and it tends to remain rather than break down quickly. Homeowners in Middle River often hear about PFUnA after a utility notice, local reporting, or private lab testing; when that happens, it’s sensible to consider treatment options meant to reduce PFAS specifically.
Because PFUnA is usually found at very low concentrations, you’re unlikely to detect it by smell, taste, or sight, which makes testing the only reliable way to know what’s in your tap water. PFAS such as PFUnA act differently from familiar issues like chlorine taste, sediment, or the hard water that’s common across northeast Florida, so a standard point-of-use cartridge may not be adequate. For many Middle River homes, a whole-house strategy is a practical choice to lower exposure from drinking, cooking, showering and everyday household use.
For whole-home reduction of PFUnA, a high-quality granular activated carbon (GAC) filter is widely regarded as the most effective single-filter residential option. Carbon media offers extensive surface area to adsorb many organic contaminants, including a variety of PFAS. Effective PFUnA removal relies on using the appropriate carbon type, ensuring enough contact time, and controlling flow rates—so a correctly sized whole-house carbon tank generally performs better than a small, fast-flow cartridge in a Middle River household.
Mr. Pure Water typically installs whole-house GAC systems at the point where water enters Middle River homes so every tap and appliance receives treated water. We size systems to match household water use—important in this part of St. Johns County where hard water can contribute to limescale—because short contact time reduces PFAS capture. Carbon media also needs routine maintenance and scheduled replacement as it becomes loaded; if you have recent test results, we’ll use them to recommend the proper configuration for PFUnA reduction.
