Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS compounds people read about when investigating persistent contaminants in drinking water. It can reach water supplies through industrial usage and the breakdown of related fluorinated chemicals, and it does not break down quickly once present. Rosedale homeowners commonly hear about PFUnA after a utility advisory, local reporting, or private testing, and if you’re worried it’s best to look at treatment methods that specifically target PFAS.
Because PFUnA generally appears at very low concentrations, you won’t be able to detect it by sight, smell, or taste in tap water — which makes testing important to understand what’s coming into your Rosedale home. PFAS such as PFUnA behave differently from familiar issues like chlorine taste, sediment, or scale from hard water, so standard cartridge filters alone may not be sufficient. A whole-house solution can help reduce exposure during drinking, cooking, showering, and everyday use.
For whole-house reduction of PFUnA, the most effective single-filter residential option is a granular activated carbon (GAC) tank. Carbon media offers a very large surface area that can adsorb many organic contaminants, including a variety of PFAS. Effectiveness against PFUnA depends on selecting the right carbon type, ensuring enough contact time, and keeping appropriate flow rates — which is why a properly sized whole-house carbon tank usually outperforms a small, fast-flow cartridge.
Mr. Pure Water typically installs a whole-house GAC system at the point where water enters Rosedale homes so every tap and appliance receives treated water. We size the system based on household water use to avoid short contact times that can reduce PFAS adsorption, and like all adsorption media, the carbon must be maintained and replaced on a schedule as it becomes loaded. If you have recent water test results, we’ll use them to recommend the ideal GAC configuration for reducing PFUnA.
