Including filter system and high-performance 4:2 FTS filter.
4:2 FTS is one of the PFAS chemicals that can migrate into water supplies over time. In Old Town, homeowners commonly find out about these contaminants through a utility notice, a private well test, or during a real estate water inspection. Because 4:2 FTS is invisible and tasteless, many families prefer to take steps to limit exposure and feel confident about the water they use for drinking, cooking and bathing. Tackling it effectively begins with treatment designed for PFAS, not just basic sediment or taste filters.
Since 4:2 FTS belongs to the larger PFAS group, lab reports may list it alongside other fluorinated compounds even when it’s the primary concern. Standard carbon taste filters, water softeners and simple sediment cartridges don’t reliably remove PFAS on their own. For Old Town homes, the most dependable strategy is whole-house treatment at the main line so every faucet and appliance is covered — rather than depending only on an under-sink unit for peace of mind.
To reduce 4:2 FTS throughout your Old Town residence, the best single whole-home option is a high-capacity granular activated carbon (GAC) system sized and specified for PFAS removal. Activated carbon can adsorb many PFAS compounds, but its effectiveness relies on having sufficient carbon volume and contact time as water passes through the tank. That’s why a full-size tank-based or backwashing GAC unit usually performs better for whole-home reduction than small inline cartridges. Correct sizing also extends media life and keeps performance steady between services.
A whole-house GAC filter is plumbed on the main water line so showers, sinks, laundry and the kitchen all receive treated water in Old Town. These systems are commonly paired with a prefilter to remove sediment and protect the carbon bed from clogging and channeling. For contaminants like 4:2 FTS, routine maintenance matters as much as the initial install because spent carbon will no longer adsorb PFAS effectively. Mr. Pure Water can help Old Town homeowners choose the right carbon unit for their household flow rates and water conditions to deliver consistent, house-wide protection.
