Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS compounds people ask about when researching persistent contaminants that are hard to remove from drinking water. It can reach water supplies through industrial use and the gradual breakdown of related fluorinated chemicals, and it tends to persist rather than break down quickly. Highland homeowners often hear about PFUnA after news stories, utility communications, or private testing — and when that happens, the most useful next step is to consider treatment options specifically aimed at reducing PFAS.
Because PFUnA is usually present at very low concentrations, it won’t change the smell, taste, or appearance of your water, which makes it difficult to detect without a test. PFAS like PFUnA behave differently than familiar issues such as chlorine taste, sediment, or hard water, so a basic pitcher or inline cartridge often won’t address them. For Highland homes, a whole-house strategy can be a practical way to lower exposure from drinking, cooking, showering, and everyday use throughout the property.
When treating PFUnA for an entire home, a high-quality granular activated carbon (GAC) filter is commonly the most effective single-filter choice in residential systems. Carbon media offers a very large surface area that can adsorb many organic contaminants, including several PFAS. Effectiveness against PFUnA depends on using the right carbon type, ensuring adequate contact time, and controlling flow rates — which is why a correctly sized whole-house carbon tank typically outperforms a small, fast-flow cartridge.
At Mr. Pure Water we often install whole-house GAC systems at the main water entry so treated water serves every tap in Highland homes. Systems are sized to match household water use and avoid short contact times that reduce PFAS uptake. Like any adsorption media, carbon needs routine maintenance and periodic replacement as it becomes saturated. If you have recent test results, we’ll review them and recommend the appropriate whole-house GAC configuration for PFUnA reduction.
