Including filter system and high-performance 4:2 FTS filter.
4:2 FTS is one member of the PFAS family that can travel through soil and groundwater, sometimes appearing in household supplies. In Sanborn you might first hear about it from a utility notice, a private well test, or during a real estate inspection. Because 4:2 FTS is invisible and has no taste, many families prefer to reduce their exposure and feel confident about the water they use for drinking, cooking and bathing. Addressing it effectively means picking treatment designed specifically for PFAS removal instead of relying only on basic sediment or taste filters.
Since 4:2 FTS belongs to the broader PFAS group, reports often mention it alongside other fluorinated compounds even when it’s the specific chemical detected. Typical carbon taste filters, water softeners, and sediment cartridges aren’t built to remove PFAS reliably. For Sanborn homes, the most dependable strategy is point-of-entry treatment so every tap and appliance is covered, rather than depending solely on a single under-sink filter for peace of mind throughout the house.
When the goal is whole-home reduction of 4:2 FTS, the best single filter type is a high-capacity granular activated carbon (GAC) system sized and specified for PFAS treatment. Activated carbon can adsorb many PFAS compounds, but how well it works depends on having sufficient carbon volume and contact time as water moves through the tank. That’s why a full-size, tank-based or backwashing GAC unit is often preferable to small inline cartridges for meaningful, home-wide reduction; proper sizing also extends media life and keeps performance steady between services.
A whole-house GAC unit is mounted on the main water line to treat showers, faucets, laundry and kitchen supplies in every Sanborn home. These systems are normally used with a prefilter to trap sediment and protect the carbon bed from clogging or channeling. For contaminants like 4:2 FTS, routine maintenance matters as much as correct installation, because spent carbon stops adsorbing PFAS.
