Including filter system and high-performance 4:2 FTS filter.
4:2 FTS is one of the PFAS chemicals that can travel through the environment and sometimes show up in local water supplies. In Richter Crossroads, homeowners often first hear about it from a utility notice, a private well test, or during a real estate inspection. You won’t be able to see or taste 4:2 FTS, but many residents prefer to reduce exposure and have greater confidence in the water they use for drinking, cooking, and bathing. Starting with treatment designed specifically for PFAS — rather than only sediment or basic taste filters — is the usual first step.
Because 4:2 FTS belongs to the wider PFAS family, it’s often mentioned alongside other fluorinated compounds on reports and notices. Typical carbon taste filters, water softeners, and sediment cartridges aren’t built to reliably remove PFAS. The most dependable solution for Richter Crossroads houses is whole-home treatment at the main water entry so every tap and appliance is covered, rather than depending solely on a single under-sink faucet filter for peace of mind.
To reduce 4:2 FTS throughout a house, the best single whole-house option is a high-capacity granular activated carbon (GAC) system sized and configured for PFAS removal. Activated carbon can adsorb many PFAS compounds, but its effectiveness relies on having sufficient carbon volume and enough contact time as water passes through the tank. For this reason, full-size tank-based or backwashing GAC units are generally a better match for Richter Crossroads homes than small inline cartridges when meaningful whole-home reduction is the goal; correct sizing also helps the media perform consistently between service visits.
A whole-house GAC system is installed on the main water line so showers, sinks, laundry and the kitchen receive treated water simultaneously. These systems are typically used with a sediment prefilter to protect the carbon bed from clogging and channeling. For contaminants like 4:2 FTS, routine maintenance matters because spent carbon can no longer adsorb PFAS effectively. Mr. Pure Water works with Richter Crossroads homeowners to size and match the right carbon system to a home’s flow and water conditions so you get reliable, house-wide treatment.
