Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS people ask about when researching persistent, hard-to-remove chemicals in drinking water. It can enter sources through industrial uses and the breakdown of related fluorinated compounds, and it does not break down quickly. Greenwood homeowners often hear about PFUnA after a utility notice, local reporting, or a private lab test, and if it’s on your mind it’s useful to consider treatment options that target PFAS specifically.
Because PFUnA is usually present at very low levels, it won’t change the smell, taste, or appearance of tap water, which makes testing the only reliable way to know if it’s present in your Greenwood supply. PFAS like PFUnA behave differently than familiar problems such as chlorine, sediment, or hard water, so standard cartridge filters often won’t be enough. For many Greenwood households, a whole-house strategy can reduce exposure during drinking, cooking, bathing, and everyday use.
When treating PFUnA for an entire house, a high-quality granular activated carbon (GAC) filter is commonly the most effective single-filter residential choice. GAC media offers large surface area that adsorbs many organic compounds, including certain PFAS, and PFUnA removal depends on using the appropriate carbon type, providing sufficient contact time, and maintaining suitable flow rates. That’s why a properly sized whole-house carbon tank usually outperforms a small, fast-flow cartridge for this contaminant.
At Mr. Pure Water we typically install whole-house GAC systems at the point where water enters Greenwood homes so every tap and appliance receives treated water. Systems are chosen to match household water use to prevent short contact time, which can lower PFAS capture, and the carbon media must be serviced and replaced on schedule as it becomes loaded. If you have a recent water test from Greenwood, we can use those results to recommend the right GAC configuration for PFUnA reduction.
