Including filter system and high-performance PFUnA filter.
PFUnA is one of the per- and polyfluoroalkyl substances homeowners ask about when investigating persistent, hard-to-remove contaminants in drinking water. It can enter sources through industrial uses and the breakdown of related fluorinated compounds and is known for lingering rather than breaking down quickly. In Capitola many residents first hear about PFUnA from utility communications, news stories, or private testing—if you’re worried, focus on treatment options designed specifically to reduce PFAS.
Because PFUnA is usually found at very low concentrations, you won’t detect it by sight, smell, or taste, which makes testing the only reliable way to know what’s in your tap water. PFAS like PFUnA don’t behave like familiar issues such as chlorine, sediment, or hard water, so simple cartridge filters often won’t be sufficient. For Capitola homeowners, a whole-house solution can be an effective way to limit exposure during drinking, cooking, showering, and daily use.
When treating PFUnA for the whole home, a high-quality granular activated carbon (GAC) filter is commonly the single most effective residential option. GAC media provides a very large surface area that adsorbs many organic contaminants, including a range of PFAS. For PFUnA specifically, results depend on choosing the right carbon type, ensuring adequate contact time, and maintaining appropriate flow rates—so a correctly sized whole-house carbon tank typically outperforms a small, fast-flow cartridge.
Mr. Pure Water usually addresses PFUnA in Capitola homes with a whole-house GAC system installed at the main water entry 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. Like all adsorption systems, carbon must be maintained and replaced on schedule as it becomes loaded; if you have a recent water test from Capitola, we’ll use it to recommend the ideal whole-house GAC configuration for PFUnA reduction.
