Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS people ask about when investigating persistent, hard-to-remove contaminants in household water. It can enter sources through industrial uses and the breakdown of related fluorinated chemicals, and it tends to persist rather than break down quickly. Plantation Key homeowners commonly hear about PFUnA from utility communications, local reporting, or private lab results — and if you’re worried, the next step is focusing on treatment methods designed to reduce PFAS specifically.
Because PFUnA usually occurs at very low levels, it won’t have a smell, taste, or visible sign in tap water — which makes testing the only reliable way to know what’s present. PFAS like PFUnA behave differently than familiar issues in the Keys such as salty corrosion, chlorine taste, or hard water, so standard cartridge filters or softeners may not address them. For Plantation Key residences, a whole-house system is often the most practical option to reduce exposure from drinking, cooking, showering, and everyday use throughout the home.
For whole-home reduction of PFUnA, a high-quality granular activated carbon (GAC) filter is the single-filter approach most commonly used in residential systems. GAC offers a very large surface area that adsorbs many organic contaminants, including various PFAS. Effectiveness for PFUnA depends on choosing the appropriate carbon type, ensuring enough contact time, and maintaining suitable flow rates — so a properly sized whole-house carbon tank typically outperforms small, fast-flow cartridges in Plantation Key settings with hard water and coastal conditions.
At Mr. Pure Water we typically install a whole-house GAC system at the point where water enters the house so treated water reaches every tap and appliance in Plantation Key. Systems are sized to match household demand to avoid short contact time that can reduce PFAS capture, and carbon media must be maintained and replaced on schedule as it becomes saturated. If you have recent test results from a Plantation Key sample, we’ll use them to recommend the right GAC configuration for PFUnA reduction.
