Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS chemicals people ask about when researching persistent, hard-to-remove contaminants in household water. It can get into water supplies from industrial uses or the breakdown of related fluorinated compounds and tends to remain rather than break down quickly. In Sears and nearby Osceola County communities, homeowners often hear about PFUnA after a utility notice, news coverage, or private testing. If you’re worried, the best next step is to consider treatments specifically designed to reduce PFAS.
Because PFUnA usually occurs at very low levels, you generally won’t be able to see, smell, or taste it in your tap water, which makes testing important to know what’s actually in your supply. PFAS like PFUnA act differently from familiar issues such as chlorine, sediment, or the mineral-driven hardness common in Central Florida groundwater, so simple cartridge filters often aren’t enough. For Sears homeowners who want protection for drinking, cooking and bathing, a whole-house solution is a practical way to reduce overall exposure.
For whole-house reduction of PFUnA, a high-quality granular activated carbon (GAC) filter is the most effective single-filter choice used in residential systems. GAC media provide extensive surface area that adsorbs many organic contaminants, including various PFAS. Effectiveness against PFUnA relies on using the right carbon type, ensuring adequate contact time, and controlling flow rates—so a properly sized whole-house carbon tank usually performs better than a small, fast-flow cartridge in a Sears home.
Mr. Pure Water recommends installing a whole-house GAC system at the main water entry so treated water protects every tap and appliance in your Sears residence; sizing is chosen to avoid short contact times that reduce PFAS capture. As with all adsorption systems, the carbon media needs regular maintenance and timely replacement to remain effective as it becomes loaded. If you have recent water test results from Osceola County or a private lab, we’ll use them to recommend the best GAC configuration for PFUnA reduction.
