Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS chemicals people ask about when investigating persistent contaminants in drinking water. It can reach water supplies from industrial uses and the breakdown of related fluorinated compounds, and it is known to persist rather than break down quickly. In Redland and the surrounding Miami‑Dade County area, homeowners often hear about PFUnA after utility notifications, local news coverage, or private well testing. If you’re worried, it’s sensible to consider treatment options that are intended specifically to reduce PFAS compounds.
Because PFUnA is generally present at very low levels, you won’t detect it by sight, smell, or taste — even in hard groundwater like much of South Miami‑Dade. That uncertainty makes testing important to know what’s actually coming from your tap. PFAS such as PFUnA don’t act like familiar issues—chlorine taste, sediment, or scale from hard water—so standard cartridge filters often won’t address them. For Redland homeowners who want to protect drinking, cooking, and shower water throughout the house, a whole‑house solution is often a practical choice.
For whole‑house reduction of PFUnA, a high‑quality granular activated carbon (GAC) filter is commonly the single most effective residential option. GAC’s large surface area adsorbs many organic compounds, including a range of PFAS. Effectiveness for PFUnA depends on using the right carbon type, providing sufficient contact time, and maintaining appropriate flow rates — which is why a properly sized whole‑house carbon tank typically outperforms a small, fast‑flow cartridge in Redland homes.
At Mr. Pure Water we usually address PFUnA with a whole‑house GAC system installed at the point where water enters the property so every tap and appliance in Redland receives treated water. Systems are chosen based on household water use and local conditions — including the hard groundwater common in South Miami‑Dade — to avoid short contact times that reduce PFAS capture. Carbon media requires scheduled maintenance and media replacement as it becomes loaded; if you have recent test results, we’ll use them to recommend the right GAC configuration for PFUnA reduction.
