Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS chemicals people investigate when they’re concerned about persistent, hard-to-remove contaminants in drinking water. It can reach water supplies through industrial uses and the breakdown of related fluorinated compounds, and it tends to persist rather than break down quickly. In City Point many residents first hear about PFUnA from utility notices, local reporting, or private well tests; if you’re worried, focus on treatment technologies that specifically target PFAS reduction.
Because PFUnA is generally present at very low concentrations, you’re unlikely to notice it by smell, taste, or sight in your tap water. That makes testing the only reliable way to know what’s actually in the water. PFAS compounds like PFUnA also behave differently from familiar concerns such as chlorine taste, visible sediment, or the hard-water scale that many City Point homes experience, so basic cartridge filters often won’t be enough. A whole-house solution can be a sensible choice to reduce exposure from drinking, cooking, showering, and everyday use.
For whole-house reduction of PFUnA, a high-quality granular activated carbon (GAC) filter is widely regarded as the most effective single-filter option for residential systems. Carbon media provides very large surface area to adsorb many organic compounds, including various PFAS. Performance against PFUnA depends on using the right carbon type, allowing adequate contact time, and keeping appropriate flow rates—so a correctly sized whole-house carbon tank typically performs better than a small, fast-flow cartridge.
At Mr. Pure Water we install whole-house GAC systems at the point where water enters City Point homes so treated water reaches every tap and appliance; system sizing takes into account household water use and local conditions like hard water to avoid short contact times that can reduce PFAS capture. Carbon media must be serviced and replaced on schedule to maintain consistent removal as the media loads up. If you have recent test results, bring them to us and we’ll recommend the right GAC configuration for PFUnA reduction.
