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 drinking water. It can reach water supplies through industrial uses and breakdown of related fluorinated compounds, and it tends to persist rather than break down quickly. In New York many homeowners first hear about PFUnA from a utility notice, local reporting, or a private lab test. If it’s on your mind, focus on treatment options that are designed specifically to reduce PFAS.
Because PFUnA is usually found at very low concentrations, you normally won’t detect it by sight, smell, or taste — which makes testing the only reliable way to know what’s in your tap water in New York. PFAS such as PFUnA also act differently than everyday issues like chlorine taste, sediment, or hard water, so standard cartridge filters often won’t be sufficient. For homeowners across New York, a whole-house system can be a sensible choice to lower exposure during cooking, bathing, and other household uses.
When addressing PFUnA for an entire home, a high-quality granular activated carbon (GAC) filter is commonly the most effective single-filter option used in residential whole-house systems. Carbon media offers large surface area to adsorb many organic compounds, including various PFAS. Effectiveness against PFUnA depends on using the right carbon type, ensuring adequate contact time, and maintaining appropriate flow rates — so a properly sized whole-house carbon tank generally outperforms a small, fast-flow cartridge.
At Mr. Pure Water we commonly treat PFUnA in New York homes with a whole-house GAC system installed at the point where water enters the house so every faucet and appliance gets treated water. Systems are chosen based on household water use to avoid short contact time that can reduce PFAS capture. Like all adsorption media, carbon must be maintained and replaced on schedule as it becomes loaded to keep performance consistent. If you have recent test results, we’ll use them to recommend the right GAC configuration for reducing PFUnA.
