Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS chemicals 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 compounds and tends to persist rather than break down quickly. Allentown residents often first hear about PFUnA from utility notices, local news, or private testing; if you’re concerned, it makes sense to concentrate on treatment options specifically designed to reduce PFAS.
Because PFUnA usually occurs at very low concentrations, you won’t be able to see, smell, or taste it in your tap water, which can make it hard to know what’s actually in your supply without testing. PFAS like PFUnA behave differently than everyday water issues such as chlorine taste, sediment, or hardness, so simple cartridge filters often aren’t sufficient. For many Allentown households, a whole-house solution provides protection for drinking, cooking, showering, and other daily uses.
For whole-home reduction of PFUnA, a high-quality granular activated carbon (GAC) filter is the most effective single-filter residential choice. GAC media offers a very large surface area that can adsorb many organic compounds, including various PFAS. With PFUnA, how well the system works depends on using the right carbon type, allowing enough contact time, and maintaining appropriate flow rates—so a properly sized whole-house carbon tank matters more than a small, fast-flow cartridge.
At Mr. Pure Water we typically install a whole-house GAC system at the main water entry so every tap and appliance in an Allentown home gets treated water. We size systems to match household water use to avoid short contact times that can reduce PFAS adsorption. Like all adsorption media, carbon needs regular maintenance and timely replacement as it becomes loaded. If you have a recent water test from your Allentown property, we can use those results to recommend the right whole-house GAC configuration for PFUnA reduction.
