Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS chemicals homeowners hear about when investigating persistent, hard-to-remove contaminants in drinking water. It can enter sources through industrial uses or the breakdown of related fluorinated compounds and tends to persist rather than break down quickly. Residents of Ferry Pass sometimes become aware of PFUnA from news coverage, utility notices, or private well testing — and if you’re worried, the practical next step is looking at treatments designed specifically to reduce PFAS.
Because PFUnA is usually present 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 act differently than common local issues such as chlorine taste or hard water, so standard cartridge filters often don’t offer adequate protection. For Ferry Pass households wanting coverage for drinking, cooking, showering and everyday use, a whole-house solution is a sensible option.
For whole-house reduction of PFUnA, the most effective single-filter choice in residential systems is a high-quality granular activated carbon (GAC) tank. Carbon media provides a very large surface area to adsorb many organic compounds, including various PFAS. How well it works for PFUnA depends on using the right carbon type, ensuring enough contact time, and maintaining appropriate flow rates — which is why a correctly sized, whole-house carbon tank outperforms small, fast-flow cartridges.
At Mr. Pure Water we install whole-house GAC systems at the point where water enters a Ferry Pass home so treated water is available at every tap and appliance. We size systems to match household water use to avoid short contact times that reduce PFAS adsorption. Like all adsorption media, the carbon needs routine maintenance and replacement as it becomes loaded to keep removal reliable — if you have a recent test, bring it to us and we’ll recommend the right GAC configuration for PFUnA reduction.
