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 groundwater and other sources through industrial uses or the breakdown of related fluorinated compounds, and it tends to persist rather than break down quickly. In Jay Jay many people first learn about PFUnA from a private well test, a utility notice, or local reporting; if it’s a concern at your address, concentrate on treatment options designed specifically for reducing PFAS.
Because PFUnA is usually found at very low levels, you won’t detect it by sight, smell, or taste — so testing is the only reliable way to know what’s in your tap water. PFAS like PFUnA act differently from common issues such as chlorine, sediment, or moderate hard water, and typical cartridge filters often aren’t sufficient. For Jay Jay homes served by groundwater wells or local utilities, a whole-house solution can be the most practical way to lower exposure during drinking, cooking, showering, and everyday use.
For whole-house reduction of PFUnA, a granular activated carbon (GAC) filter is the most effective single-filter choice commonly used in residences. GAC media provides a very large surface area that can adsorb many organic contaminants, including certain PFAS. Successful removal of PFUnA depends on selecting the right carbon type, allowing adequate contact time, and using appropriate flow rates — which is why a properly sized whole-house carbon tank outperforms a small, fast-flow cartridge in many Jay Jay properties.
At Mr. Pure Water we typically address PFUnA with a whole-house GAC system installed at the point where water enters the home so treated water reaches every tap and appliance. We size systems for your household’s water use to avoid short contact times that can reduce PFAS capture, and we emphasize scheduled carbon maintenance and replacement so performance stays consistent as the media loads. If you have a recent water test for your Jay Jay address, bring it to us and we’ll recommend the right GAC configuration for PFUnA reduction.
