Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS members homeowners hear about when researching persistent, hard-to-remove contaminants in drinking water. It can arrive in water supplies through industrial activity or the breakdown of related fluorinated chemicals and tends to persist rather than break down quickly. In Kern many residents first learn about PFUnA from utility notices, local reporting, or private well testing; if you’re worried, the best next step is to consider treatment options that specifically target PFAS.
Because PFUnA is usually present at very low levels, it won’t have a distinct smell, taste, or appearance, which makes testing the only reliable way to know what’s in your tap water in Kern. PFAS behave differently than familiar issues like chlorine, sediment, or hard-water minerals, so standard pitcher or cartridge filters often won’t be sufficient. For many Kern households, a whole-house solution is a practical option to reduce exposure from drinking, cooking, and showering throughout the home.
When a single residential filter is used for whole-house PFUnA reduction, high-quality granular activated carbon (GAC) is commonly the most effective choice. GAC media provides a large surface area that can adsorb many organic compounds, including various PFAS. Effectiveness against PFUnA depends on selecting the right carbon type, ensuring adequate contact time, and controlling flow rates—so a properly sized whole-house carbon tank usually outperforms small, fast-flow cartridges.
At Mr. Pure Water we install whole-house GAC systems at the point where water enters Kern homes so every tap and appliance receives treated water. System sizing is based on household water use to prevent short contact times that can reduce PFAS adsorption. Like all adsorption media, carbon requires scheduled maintenance and replacement as it becomes loaded to maintain performance. If you have recent test results from a Kern sample, we’ll use them to recommend the right whole-house GAC configuration for PFUnA reduction.
