Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS people ask about when researching persistent, slow-to-breakdown contaminants in drinking water. It can reach water supplies from industrial sources or through the degradation of related fluorinated chemicals, and it tends to remain rather than disappear quickly. In Oakland many homeowners first hear about PFUnA from a utility notice, local reporting, or private testing. If you’re concerned, it’s best to consider treatment options that specifically target PFAS removal.
Because PFUnA is usually found at very low levels, you won’t detect it by smell, taste, or appearance, which makes testing the only reliable way to know what’s in your tap water. PFAS such as PFUnA act differently than common local issues like the moderate hardness in Orange County water or chlorine residuals, so simple cartridge filters often aren’t sufficient. For Oakland homes a whole-house solution can be a practical way to reduce exposure during drinking, cooking, bathing, and everyday use—especially in humid Central Florida plumbing where maintenance matters.
For whole-home reduction of PFUnA, a high-quality granular activated carbon (GAC) system is generally the most effective single-filter choice for residential use. Carbon media offers a very large surface area that adsorbs many organic compounds, including various PFAS. Effective PFUnA removal relies on the right carbon type, adequate contact time, and controlled flow rates—so a properly sized whole-house carbon tank is often far more effective than a small, fast-flow cartridge in an Oakland household.
Mr. Pure Water typically installs a whole-house GAC tank at the main water entry to treat every tap in Oakland homes, sizing systems by household demand to ensure sufficient contact time for PFUnA capture. Like all adsorption systems, the carbon media needs regular maintenance and periodic replacement as it loads up to maintain performance. If you’ve already had a recent water test, we’ll use those results to recommend the right GAC configuration for your home.
