Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS chemicals homeowners hear about when researching persistent contaminants in drinking water. It can reach water supplies through industrial uses and from the breakdown of related fluorinated compounds, and it does not break down readily. Residents in Cosson Mill may first encounter concerns about PFUnA via a utility notice, media coverage, or a private lab report; when that happens it’s useful to consider treatment strategies that specifically target PFAS removal.
Because PFUnA is usually found at very low concentrations, it won’t give off an obvious odor, taste, or visible sign in your tap water, which makes testing important to understand what’s present. PFAS such as PFUnA behave differently than common household water issues like chlorine taste, sediment, or hardness, so simple cartridge filters may not be adequate. For Cosson Mill homes, a whole-house solution is a practical way to reduce exposure from drinking, cooking, bathing and other daily uses.
For whole-house reduction of PFUnA, a granular activated carbon (GAC) tank is widely considered the most effective single-filter residential option. GAC media offers a very large surface area that adsorbs many organic contaminants, including various PFAS. Success with PFUnA depends on using the appropriate carbon type, allowing enough contact time, and sizing the system to maintain favorable flow rates—so a correctly sized whole-house carbon tank will generally outperform a small, fast-flow cartridge.
Mr. Pure Water typically installs whole-house GAC systems at the main water entry for Cosson Mill homes so every tap and appliance receives treated water. We size systems based on household water use to avoid short contact times that can reduce PFAS adsorption, and we emphasize routine maintenance and media replacement because carbon performance declines as it becomes loaded. If you’ve got a recent water test from Cosson Mill, we can review it and recommend the right GAC configuration to address PFUnA.
