Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS chemicals people ask about when they’re worried about persistent contaminants in their water. It can get into sources through industrial uses or the breakdown of related fluorinated compounds and tends to persist rather than break down quickly. In Jessie Willies many homeowners first hear about PFUnA from news coverage, a utility notice, or private lab results; if it’s a concern for your household, it’s best to focus on treatment options made to reduce PFAS specifically.
Because PFUnA is usually found at very low levels, you’re unlikely to detect it by sight, smell, or taste — which makes testing the reliable way to know what’s in your tap water. PFAS like PFUnA behave differently than common local issues such as chlorine taste or sediment, so simple cartridge filters often won’t provide the protection people expect. A whole-house system can offer broader coverage in Jessie Willies, treating water used for drinking, cooking, showering, and everyday household tasks.
For whole-house reduction of PFUnA, a well-designed granular activated carbon (GAC) filter is widely recognized as the most effective single-filter residential option. GAC media provides a very large surface area that adsorbs many organic contaminants, including various PFAS. Performance against PFUnA depends on using the right carbon type, allowing sufficient contact time, and maintaining appropriate flow rates — which is why a correctly sized whole-house carbon tank generally outperforms small, fast-flow cartridges.
At Mr. Pure Water we install whole-house GAC systems at the point where water enters Jessie Willies homes so treated water reaches every tap and appliance. Systems are chosen to match household water use to avoid short contact times that can reduce PFAS capture. Like all adsorption media, carbon needs scheduled maintenance and replacement as it becomes loaded to preserve performance. If you have recent test results, bring them to us and we’ll recommend the right GAC configuration for PFUnA reduction.
