Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS compounds homeowners hear about when investigating persistent, difficult-to-treat contaminants in drinking water. It can reach water supplies from industrial applications and the breakdown of related fluorinated chemicals, and it tends to persist rather than break down quickly. Residents of Fidelis may first learn about PFUnA through a utility notice, news coverage, or a private lab result; if you’re worried, the practical next step is considering treatment options designed specifically to reduce PFAS.
PFUnA often occurs at levels too low to detect by taste, smell, or sight, so regular household senses won’t reveal whether it’s present in your Fidelis tap water. That invisibility makes testing important if you want to know what’s coming from your pipes. PFAS such as PFUnA behave differently from familiar problems like chlorine taste, visible sediment, or hard water, and standard point-of-use cartridges may not be sufficient — a whole-house solution can more reliably limit exposure during drinking, cooking, showering, and everyday chores.
For whole-house reduction of PFUnA, homeowners in Fidelis most often choose a granular activated carbon (GAC) tank as the single most effective residential filter. GAC media offers a very large surface area that adsorbs many organic contaminants, including a range of PFAS compounds. Effectiveness against PFUnA depends on using the appropriate carbon type, allowing enough contact time, and maintaining proper flow rates — which is why a correctly sized whole-house carbon system is generally preferable to a small, fast-flow cartridge.
Mr. Pure Water typically installs a whole-house GAC system at the main water entry so treated water reaches every faucet and appliance in Fidelis homes. We size systems to match household water use to avoid short contact times that can reduce PFAS removal. As with all adsorption media, the carbon must be serviced and replaced on schedule because its capacity diminishes as it becomes loaded. If you have recent test results from your Fidelis property, we’ll use them to recommend the best configuration for reducing PFUnA.
