Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS people ask about when investigating persistent contaminants in household water. It can come into water supplies from industrial uses and the breakdown of related fluorinated chemicals, and it does not break down quickly. In Bear Hollow many homeowners first hear about PFAS from local advisories, media coverage, or private testing; if it’s a concern for you, consider focusing on treatment methods designed to reduce PFAS specifically.
PFUnA is generally found at very low concentrations, so you won’t notice it by sight, smell, or taste — which makes testing the only reliable way to know what’s in your water. PFAS like PFUnA act differently from everyday water problems such as chlorine, sediment, or the hard water common in our limestone aquifer-fed systems, so standard cartridge filters often aren’t enough. For Bear Hollow households a whole-house strategy can help lower exposure from drinking, cooking, showering, and other daily uses.
When reducing PFUnA throughout a home, a high-quality granular activated carbon (GAC) whole-house filter is the most effective single-filter residential option. GAC offers a very large surface area that adsorbs many organic compounds, including various PFAS. Effectiveness for PFUnA depends on using the right carbon type, providing adequate contact time, and maintaining appropriate flow rates — which is why a correctly sized whole-house carbon tank typically outperforms small, fast-flow cartridges.
At Mr. Pure Water we install whole-house GAC systems at the point where water enters the home so treated water protects every tap and appliance in Bear Hollow. We size systems based on your household’s water use to prevent too-short contact time, which can reduce PFAS removal. Like all adsorption media, carbon must be serviced and replaced on schedule as it becomes loaded; if you have recent test results, we’ll use them to recommend the best GAC configuration for PFUnA reduction.
