Including filter system and high-performance 8:2 FTS filter.
8:2 FTS is one of the PFAS family—long-lasting, man-made compounds that can turn up in drinking water. Havana homeowners may learn about it from utility reports, local news, or private tests. Because it doesn’t change the smell, taste, or look of water, you can’t rely on your senses to spot it. If you’re worried about exposure in your Havana house, the sensible next step is to consider treatment that targets PFAS generally, including 8:2 FTS.
When 8:2 FTS is present in household water, it can be used for cooking, bathing, laundry, and other daily tasks. Point-of-use faucet filters only protect a single outlet, leaving the rest of a Havana home exposed. A whole-house system treats water as it enters your property so every tap and appliance receives the same treated water. That approach both reduces PFAS like 8:2 FTS throughout the home and helps protect plumbing fixtures and appliances from contaminants in the incoming supply.
For whole-house reduction of 8:2 FTS, the most effective single-filter option is a PFAS-rated activated carbon system using generous amounts of granular activated carbon (GAC). Activated carbon adsorbs many organic contaminants and is commonly used for PFAS reduction. Because members of the PFAS family behave differently, success depends on having enough carbon media and proper contact time—not a small cartridge. A correctly sized whole-house GAC filter is built to handle all the water entering a Havana residence rather than relying on individual sink filters.
A whole-house GAC filter is mounted on the main water line so treatment happens before water reaches showers, bathrooms, and appliances. Its effectiveness hinges on flow rate, water chemistry, and media age, so choosing adequate carbon capacity and scheduling timely media replacement are important. These systems are often paired with prefiltration to remove sediment that could bypass or channel the carbon bed. For consistent PFAS reduction, including 8:2 FTS, pick a system designed for whole-house flow and regular maintenance in Havana homes.
