Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS that homeowners hear about when investigating persistent, hard-to-remove contaminants in drinking water. It can reach water supplies through industrial uses and the breakdown of related fluorinated chemicals, and it does not break down quickly. In Old Grove, people often become aware of PFUnA after a private test, a utility notice, or media coverage; if it’s a concern for your household, the most useful next step is to consider treatment options that target PFAS specifically.
Because PFUnA usually occurs at very low concentrations, it’s not something you can detect by sight, taste, or smell—especially in humid subtropical communities like Old Grove where plumbing can be affected by moisture and heavy rain. PFAS such as PFUnA behave differently from everyday water issues like chlorine taste or sediment, so common cartridge filters often won’t be enough. For many Old Grove homes, a whole-house strategy offers protection for drinking, cooking, showering, and other daily uses.
For whole-house reduction of PFUnA, a high-quality granular activated carbon (GAC) filter is generally the most effective single-filter choice for residential systems. GAC provides a very large surface area that can adsorb many organic compounds, including various PFAS. Effectiveness against PFUnA depends on using the appropriate carbon type, allowing sufficient contact time, and maintaining suitable 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 main water entry so treated water reaches every tap in your Old Grove home. We size systems around household water use to prevent short contact times that can reduce PFAS adsorption. Like any adsorption media, carbon must be maintained and replaced on schedule as it becomes loaded, and if you have recent test results we’ll use them to recommend the right whole-house configuration for PFUnA reduction.
