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. In Old Town you might learn about it from a utility report, local news, or private testing, but you won’t be able to taste or see it in your water. If you’re worried about exposure in your home, the sensible step is to choose treatment that targets PFAS broadly, including 8:2 FTS.
When 8:2 FTS is present in household water, it can reach every routine use — cooking, showers, laundry, and dishwashing — unless treated. Many faucet-mounted or under-sink filters only protect a single point, leaving other taps unaddressed. In Old Town homes, a whole-house system treats water at the main line so all outlets receive filtered water, protecting fixtures and appliances as well as reducing PFAS like 8:2 FTS throughout the house.
The most effective single-filter whole-house option for reducing 8:2 FTS is a PFAS-rated activated carbon system using high-capacity granular activated carbon (GAC). GAC removes many organic contaminants by adsorption and is commonly specified for PFAS reduction. Because PFAS compounds behave differently, success depends on using sufficient carbon media and allowing proper contact time — not a small cartridge. A correctly sized whole-house GAC filter treats all incoming water to the Old Town residence rather than relying on individual sink filters.
A whole-house GAC filter is installed on the main water line so treated water reaches showers, bathrooms, and appliances throughout your Old Town home. Performance varies with flow rate, water chemistry, and how long the media has been in service, so media capacity and regular replacement are important. These systems are often paired with a sediment prefilter to prevent channeling or clogging of the carbon bed. For consistent reduction of PFAS compounds like 8:2 FTS, choose a system designed for whole-house flow and routine maintenance.
