Including filter system and high-performance PFUnA filter.
PFUnA is one member of the PFAS family homeowners hear about when investigating persistent, hard-to-remove contaminants in drinking water. It can make its way into water supplies through industrial applications and the breakdown of related fluorinated chemicals, and it tends to persist rather than dissipate quickly. Many Hathaway Mill residents first learn about PFUnA from a utility notice, local reporting, or private testing of a well or household supply. If you’re concerned, focus on treatment solutions that are specifically designed to reduce PFAS compounds.
Because PFUnA is usually found at very low concentrations, you generally won’t detect it by sight, taste, or smell, which makes testing the only reliable way to know what’s in your tap water. PFAS such as PFUnA behave differently than common problems like chlorine taste, sediment, or hardness, so typical point-of-use cartridges often aren’t sufficient. For Hathaway Mill homes, a whole-house strategy can help limit exposure during drinking, cooking, bathing, and everyday tasks throughout the house.
For whole-house reduction of PFUnA, the most effective single-filter option commonly used in homes is a granular activated carbon (GAC) system. Carbon media offers a very large surface area that adsorbs many organic contaminants, including a number of PFAS. Performance against PFUnA depends on using the right carbon type, ensuring adequate contact time, and sizing the system for the home’s flow rates. That’s why a correctly sized whole-house carbon tank typically outperforms small, fast-flow cartridges for this application.
At Mr. Pure Water we install whole-house GAC systems at the point where water enters Hathaway Mill homes so every tap and appliance receives treated water. We size systems to match household water use to avoid short contact times that can lower PFAS capture. Like all adsorption media, carbon will need routine monitoring and periodic replacement to maintain effectiveness as it becomes loaded. If you have a recent water test, bring it to us and we’ll recommend the proper GAC configuration for PFUnA reduction.
