Including filter system and high-performance 8:2 FTS filter.
8:2 FTS is one member of the PFAS family—man-made chemicals that persist in the environment and can turn up in drinking water. Duck Key homeowners often first learn about contaminants like this from utility reports, local news, or private testing. Because 8:2 FTS doesn’t change the taste, smell, or appearance of water, you won’t be able to detect it by eye or nose. If you’re worried about potential exposure here in the Florida Keys, the most practical step is to consider treatment aimed at PFAS as a group, including 8:2 FTS.
When 8:2 FTS is present in household water, it can be used for cooking, showering, laundry, and more throughout your home. Many under-sink or pitcher-style filters only protect a single faucet, leaving other taps and appliances unfiltered. A whole-house system treats incoming water for the entire property—important in Duck Key where many homes use municipal or desalinated supplies and often add filtration or softening to limit mineral scale. Treating water at the main line gives you consistent coverage for showers, dishwashers, and irrigation rather than guessing which points are protected.
For whole-house reduction of 8:2 FTS, the most effective single-filter choice is a PFAS-rated activated carbon system—generally a high-capacity granular activated carbon (GAC) unit. Activated carbon adsorbs a range of organic contaminants and is commonly used for PFAS removal in residential and utility applications. Because PFAS compounds behave differently, success depends on having ample carbon media and sufficient contact time—so a large, properly sized GAC system is preferable to a small cartridge for treating an entire Duck Key home.
A whole-house GAC filter is installed at the main water line so treated water reaches showers, bathrooms, and appliances across your Duck Key property. Its effectiveness depends on flow rate, water chemistry (including the hard water many Keys homes experience), and media age, so capacity and timely media replacement are important. These systems are often paired with prefiltration to catch sediment that could channel or foul the carbon bed. For reliable PFAS reduction—including 8:2 FTS—choose a unit sized and maintained for whole-house flow rather than a single-point cartridge.
