Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS chemicals people research when they’re worried about persistent contaminants in their drinking water. It can reach water supplies through industrial uses and the gradual breakdown of related fluorinated compounds, and it doesn’t break down quickly on its own. Bascom homeowners often hear about PFUnA after a utility advisory, a news story, or from results of a private well test; if you’re concerned, the best step is to consider treatment options that specifically target PFAS.
Because PFUnA is usually found at very low concentrations, it typically won’t change the taste, smell, or appearance of your water — which makes testing the only reliable way to know whether it’s present. PFAS like PFUnA behave differently from familiar issues such as chlorine taste, sediment, or hard water, so common cartridge filters may not provide adequate protection. For many Bascom households, a whole-house solution is a practical way to reduce exposure during drinking, cooking, showering, and daily use.
For whole-house reduction of PFUnA, the most effective single-filter choice in residential systems is a granular activated carbon (GAC) tank. GAC media offers a very large adsorption surface that can capture many organic contaminants, including various PFAS. Effectiveness against PFUnA depends on using the right carbon type, allowing sufficient contact time, and keeping flow rates within design limits — which is why a correctly sized whole-house carbon tank is usually preferable to a small, fast-flow cartridge.
Mr. Pure Water installs whole-house GAC systems at the main water entry so treated water serves every tap in Bascom homes. We size systems to match household water use to avoid short contact times that reduce PFAS capture, and we emphasize routine maintenance and timely media replacement so removal stays consistent as the carbon loads. If you have recent test results from your Bascom well or utility, we can use them to recommend the optimal GAC configuration for PFUnA reduction.
