Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS chemicals homeowners hear about when researching persistent, hard-to-treat contaminants in drinking water. It can reach water supplies through industrial uses and the breakdown of related fluorinated substances, and it tends to persist rather than break down quickly. Many Hurlburt Field residents first learn about PFUnA from utility notices, local reporting, or private testing. If you’re concerned, it’s useful to consider treatment options that are specifically aimed at reducing PFAS.
Because PFUnA is usually found at very low levels, you most likely won’t be able to see, smell, or taste it in your water at Hurlburt Field — which makes testing important if you want to know what’s coming from the tap. PFAS like PFUnA behave differently than familiar issues such as chlorine, sediment, or hard water, so simple cartridge filters often won’t provide adequate protection. A whole-house system can be a sensible choice to lower exposure from drinking, cooking, showering, and everyday household use.
For whole-house reduction of PFUnA, residential systems most often rely on a granular activated carbon (GAC) filter as the single best filter option. GAC media offers a very large surface area that can adsorb many organic contaminants, including various PFAS. Effectiveness for PFUnA depends on using the appropriate carbon type, giving the water enough contact time, and controlling flow rates—so a properly sized whole-house carbon tank typically performs better than a small, fast-flow cartridge.
At Mr. Pure Water we commonly install whole-house GAC systems at the main entry point so treated water reaches every tap in Hurlburt Field homes. Systems are sized to match household water use to prevent short contact times that can reduce PFAS capture. Like all adsorption media, the carbon requires scheduled maintenance and replacement as it becomes loaded to keep removal consistent. If you have a recent water test, bring it to us and we’ll recommend the right whole-house carbon configuration for PFUnA reduction.
