Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS people hear about when researching persistent, hard-to-remove contaminants in drinking water. It can get into water through industrial uses or from the breakdown of related fluorinated chemicals and tends to remain rather than break down quickly. Miami-Dade County homeowners often first notice PFUnA after a utility announcement, local news coverage, or a private water test. If you’re worried, the most useful next step is to look at treatment options specifically designed to reduce PFAS.
PFUnA is usually present at very low concentrations, so it won’t change the look, smell, or taste of your water — which makes testing important if you want to know what’s in your tap. PFAS such as PFUnA behave differently from common local issues like chlorine taste, sediment, or the hard, limescale-prone municipal water many Miami-Dade households see. Because of that, simple pitcher or cartridge filters may not be sufficient; a whole-house solution can help limit exposure when drinking, cooking, showering, and using appliances throughout your Miami-Dade home.
For whole-home PFUnA reduction, a granular activated carbon (GAC) filter is generally the most effective single-filter choice for residential systems. GAC media offers a very large surface area that adsorbs many organic contaminants, including a range of PFAS. Effectiveness against PFUnA depends on using the appropriate carbon type, ensuring enough contact time, and controlling flow rates — so a properly sized whole-house carbon tank typically outperforms small, fast-flow cartridges in Miami-Dade homes.
Mr. Pure Water installs whole-house GAC systems at the point where municipal water enters the home so treated water reaches every tap and appliance across Miami-Dade County. We size systems to match household usage to avoid the short contact times that can reduce PFAS removal. Like any adsorption media, carbon requires regular maintenance and timely replacement to maintain performance as it becomes loaded. If you have recent test results, bring them to us and we’ll recommend the right GAC configuration for PFUnA reduction in your home.
