Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS people ask about when researching persistent contaminants that resist breakdown in water. It can enter supplies through industrial uses and the degradation of related fluorinated chemicals, and it tends to remain rather than disappear quickly. Lake Mary homeowners often first hear about PFUnA from utility notices, local news, or private well testing; when that happens it’s sensible to look at treatment options that specifically target PFAS.
Because PFUnA is commonly found at very low concentrations, you’re unlikely to detect it by sight, smell, or taste in tap water — even in Lake Mary. That makes testing the only reliable way to know what’s present. PFAS like PFUnA behave differently than familiar issues such as chlorine taste, sediment, or the hard water that affects many Seminole County homes, so typical cartridge filters aren’t always sufficient. A whole-house system addresses exposure from drinking, cooking, showering and everyday use throughout the home.
For whole-house reduction of PFUnA, a granular activated carbon (GAC) filter is the most effective single-filter choice for residential systems. GAC media offers extensive surface area to adsorb many organic contaminants, including a range of PFAS. Performance against PFUnA depends on selecting the right carbon type, ensuring adequate contact time, and maintaining appropriate flow rates — which is why a correctly sized whole-house carbon tank typically outperforms small, fast-flow cartridges.
At Mr. Pure Water we commonly install whole-house GAC systems at the point where water enters Lake Mary homes so every tap and appliance receives treated water. Systems are chosen to match household demand and avoid short contact times that lessen PFAS capture — an important consideration in hard-water areas where scale can also affect plumbing and appliances. Carbon media requires routine maintenance and timely replacement to remain effective; if you have recent test results, we’ll use them to size and configure the system for PFUnA reduction.
