Including filter system and high-performance 8:2 FTS filter.
8:2 FTS is part of the PFAS family—long-lasting synthetic chemicals that sometimes turn up in drinking water. Littman homeowners may learn about it from utility reports, the news, or private testing, and because it doesn’t affect taste, smell, or appearance you can’t rely on your senses to know it’s there. If you’re worried about exposure in your Florida home, the sensible next step is selecting treatment that targets PFAS broadly, including 8:2 FTS.
When 8:2 FTS is present in household water, it can be used for cooking, bathing, laundry, and more. Many under-sink or countertop filters only protect a single faucet, leaving much of the home untreated. A whole-house system treats incoming water for all fixtures in your Littman residence so you don’t have to guess which tap is safe. That approach also helps reduce wear on plumbing and appliances by addressing contaminants at the point they enter your home.
For reducing 8:2 FTS in the whole house, the most effective single-filter choice is a PFAS-rated activated carbon system using high-capacity granular activated carbon (GAC). Activated carbon adsorbs many organic contaminants and is commonly used for PFAS reduction. Because PFAS compounds behave differently, effectiveness depends on having sufficient carbon media and enough contact time—not a small cartridge. A correctly sized whole-house GAC filter is built to handle all the water flowing into a Littman home rather than treating only one sink.
A whole-house GAC filter is installed on the main supply so water is treated before it reaches showers, bathrooms, and appliances in your Littman house. How well it reduces 8:2 FTS depends on flow rate, water chemistry, and how long the carbon has been in service, so media capacity and scheduled replacement are important. These systems are often paired with a sediment prefilter to prevent clogging or channeling of the carbon bed. For consistent PFAS reduction in Littman, choose a system sized and maintained for whole-house flow rather than relying on point-of-use cartridges.
