Including filter system and high-performance PFUnA filter.
PFUnA is one of the PFAS chemicals people ask about when researching persistent contaminants in drinking water. It can reach waterways through industrial uses and the breakdown of related fluorinated compounds, and it resists quick natural breakdown. Salem homeowners often hear about PFUnA after a utility notice, news coverage, or a private well test; if you’re concerned, it’s best to consider treatment options that specifically target PFAS removal.
Because PFUnA is usually present at very low levels, you won’t detect it by sight, smell, or taste in your tap water in Salem. That invisibility makes testing important if you want to know what’s coming from the faucet. PFAS like PFUnA act differently from familiar issues such as chlorine taste, sediment, or hard water, so standard cartridge filters may not provide reliable reduction. For many Salem households, a whole-house solution offers protection for drinking, cooking, showering, and everyday use.
When reducing PFUnA throughout the home, a granular activated carbon (GAC) filter is commonly the single-filter choice used in whole-house systems. GAC media has extensive surface area that can adsorb a variety of organic compounds, including many PFAS. Effective PFUnA reduction relies on using the appropriate carbon type, ensuring adequate contact time, and controlling flow rates — which is why a correctly sized whole-house carbon tank typically outperforms small, fast-flow cartridges.
At Mr. Pure Water in Salem, we usually address PFUnA with a whole-house GAC system installed at the main water entry so treated water reaches every tap and appliance. Systems are selected based on household water use to prevent short contact times that can reduce PFAS removal. As with any adsorption media, the carbon must be serviced and replaced on schedule to maintain performance as it becomes loaded. If you have a recent water test from Salem or the surrounding area, we’ll use it to size and recommend the right configuration for PFUnA reduction.
