Including filter system and high-performance PFUnA filter.
PFUnA is one member of the broader PFAS family homeowners hear about when researching persistent, hard-to-remove contaminants in drinking water. It can reach water supplies through industrial uses and the breakdown of related fluorinated chemicals, and it does not break down quickly. Stern residents often become aware of PFUnA after utility communications, local reporting, or private testing; if you’re worried, focusing on treatment options designed for PFAS reduction is a good next step.
Because PFUnA usually exists at very low concentrations, you won’t detect it by sight, smell, or taste — which makes testing the only reliable way to know what’s in your tap water. PFAS like PFUnA act differently from familiar issues such as chlorine, sediment, or hard water, so typical household cartridge filters may not remove them effectively. For many Stern homes, a whole-house solution is a practical way to limit exposure during drinking, cooking, showering, and everyday use.
For whole-house reduction of PFUnA, a well-designed granular activated carbon (GAC) filter is the most effective single-filter residential option. GAC media offers extensive surface area that adsorbs many organic contaminants, including certain PFAS. Effectiveness for PFUnA depends on choosing the right carbon type, ensuring adequate contact time, and controlling flow rates — so a properly sized whole-house carbon tank typically outperforms small, fast-flow cartridge units.
Mr. Pure Water installs whole-house GAC systems at the main water entry to deliver treated water throughout Stern homes and protect every tap and appliance. We size systems around household water use to avoid overly fast flow that reduces PFAS adsorption. Like all adsorption media, carbon requires scheduled maintenance and periodic replacement to sustain performance as it loads up. If you have recent test results, bring them in and we’ll recommend the right GAC configuration for PFUnA reduction in your house.
