Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS compounds homeowners hear about when researching persistent, hard-to-treat contaminants in drinking water. It can get into water supplies through industrial uses or from the breakdown of related fluorinated chemicals, and it does not break down quickly. Residents of Douglass Crossroads may first encounter PFUnA through a utility notice, a news item, or results from a private well test; if it’s a concern, it’s most useful to look at treatment options specifically designed to reduce PFAS compounds.
Because PFUnA usually occurs at very low levels, you won’t be able to detect it by smell, taste, or sight in tap water. That makes testing the only reliable way to know what’s present in your Douglass Crossroads home. PFAS such as PFUnA act differently than familiar issues like chlorine taste, sediment, or hardness, so standard cartridge filters often aren’t sufficient. For many households, a whole-house system is a practical solution to lower exposure during drinking, cooking, bathing, and other everyday uses.
For whole-house treatment of PFUnA, a granular activated carbon (GAC) filter is the most effective single-filter option commonly used in homes. GAC media offers extensive surface area for adsorption and can capture a range of organic contaminants, including some PFAS. Effectiveness against PFUnA depends on using the appropriate carbon type, ensuring adequate contact time, and maintaining proper flow rates—so a correctly sized whole-house GAC tank typically performs better than a small, fast-flow cartridge.
At Mr. Pure Water we install whole-house GAC systems at the point where water enters Douglass Crossroads homes so treated water reaches every tap. Systems are sized for your household’s water use to preserve contact time and maximize PFAS capture, and the carbon media must be serviced or replaced on schedule as it becomes loaded. If you have recent test results, bring them to us and we’ll recommend the right GAC configuration for reducing PFUnA in your home.
