Including filter system and high-performance 8:2 FTS filter.
8:2 FTS is part of the PFAS family — long-lasting, human-made chemicals that can end up in drinking water. Blocker homeowners might learn about it from utility reports, local news, or private testing, but you won’t be able to taste, smell, or see it in your water. If you’re worried about exposure in your Blocker home, the practical step is selecting treatment designed to reduce PFAS broadly, including 8:2 FTS.
When 8:2 FTS is present in household water, it can be used for cooking, showering, laundry, and dishwashing across the home. Faucet-only (point-of-use) devices leave much of the plumbing and appliances unprotected, so many Blocker residents choose whole-house filtration instead. Treating water at the main line ensures every tap and fixture receives the same level of protection and helps guard your plumbing and appliances from contaminants in the incoming supply.
To reduce 8:2 FTS in a whole-house setup, the single most effective 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 in water treatment. Because PFAS compounds behave differently, success depends on adequate carbon media and sufficient contact time rather than a small cartridge; a correctly sized whole-house GAC unit treats all household water rather than just one sink.
A whole-house activated carbon filter is installed on the main water line so treated water reaches showers, bathrooms, and appliances throughout your Blocker home. System performance varies with flow rate, water chemistry, and the age of the carbon, so choosing sufficient media capacity and keeping to replacement schedules matters. These systems are often paired with prefiltration to remove sediment that can shorten carbon life; for consistent reduction of PFAS like 8:2 FTS, select a unit designed for whole-house flow and maintenance.
