Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS compounds homeowners hear about when researching persistent, hard-to-treat contaminants in drinking water. It can make its way into sources through industrial uses or the breakdown of related fluorinated chemicals and tends to persist instead of breaking down quickly. In Monet, residents often become aware of PFUnA after seeing local news, receiving a utility notice, or running a private well test. If you’re concerned, it’s helpful to consider treatment options that are proven for PFAS reduction rather than general-purpose filters.
Because PFUnA is usually present at very low levels, you generally won’t notice it by sight, smell, or taste — which is why testing is the only reliable way to know what’s in your water. PFAS such as PFUnA act differently than familiar problems like chlorine, sediment, or hard water, so many standard cartridge filters won’t remove them effectively. For Monet homeowners—whether on municipal supply or a private well—a whole-house solution can help reduce exposure during drinking, cooking, showering, and daily use.
For whole-house reduction of PFUnA, a well-designed granular activated carbon (GAC) filter is generally the single most effective residential option. GAC media provides a very large surface area that can adsorb a variety of organic contaminants, including certain PFAS. Performance against PFUnA depends on choosing the right carbon type, ensuring adequate contact time, and controlling flow rates—so a properly sized whole-house carbon tank is often more effective than a small, quick-flow cartridge.
Mr. Pure Water typically installs whole-house GAC systems at the main water entry point so treated water reaches every tap and appliance in Monet homes. We size systems to match household water use, helping prevent short contact times that can reduce PFAS removal, and schedule media replacement so the carbon remains effective as it becomes loaded. If you have recent test results from a municipal report or private well, we’ll use them to recommend the right GAC configuration for PFUnA reduction.
