Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS compounds 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 tends to persist rather than dissipate quickly. In New Home many homeowners first learn about PFUnA from utility notices, local reporting, or private testing. If you’re worried, it’s sensible to consider treatment methods designed specifically to reduce PFAS.
Because PFUnA is usually present only at very low concentrations, you won’t be able to see, smell, or taste it coming from the tap in New Home — which makes testing important to know what’s really in your water. PFAS such as PFUnA behave differently from common issues like chlorine taste, sediment, or hard water, so simple cartridge filters often won’t be enough. For many New Home homes, a whole-house solution is a practical way to reduce exposure during drinking, cooking, bathing, and everyday use.
For whole-house reduction of PFUnA, a high-quality granular activated carbon (GAC) filter is generally the most effective single-filter choice for residential systems. Carbon media provides extensive surface area to adsorb many organic compounds, including a range of PFAS. When targeting PFUnA, results depend on using the right carbon type, ensuring adequate contact time, and maintaining appropriate flow rates — which is why a properly sized whole-house carbon tank typically outperforms a small, fast-flow cartridge in New Home installations.
Mr. Pure Water typically treats PFUnA in New Home with a whole-house GAC system installed at the main service entrance so every tap and appliance receives treated water. We size systems to match household water use to prevent short contact times that can reduce PFAS capture. As with all adsorption media, the carbon must be serviced and replaced on schedule to maintain removal performance as it becomes loaded. If you have a recent water test from New Home, we can review it and recommend the right GAC configuration for PFUnA reduction.
