Including filter system and high-performance 4:2 FTS filter.
4:2 FTS is one of the PFAS compounds that can travel through the environment and sometimes turn up in drinking water. Chatham homeowners may hear about it from a utility notice, a private well test, or a real estate inspection, and because you can’t see or taste 4:2 FTS many residents choose to reduce exposure as a precaution. Picking the right treatment means looking beyond basic sediment or taste filters to options specifically targeted for PFAS reduction.
Because 4:2 FTS belongs to the wider family of fluorinated compounds, it’s often mentioned alongside other PFAS on reports even when it’s the compound detected. Typical carbon pitchers, softeners, and sediment cartridges aren’t built to remove PFAS reliably. For homeowners around Chatham the most sensible strategy is whole-house treatment at the main line so every tap, shower, and appliance gets treated—rather than depending only on a single under-sink filter for peace of mind.
To reduce 4:2 FTS throughout a home, the top whole-house choice is a high-capacity granular activated carbon (GAC) system sized and specified for PFAS removal. Activated carbon can adsorb many PFAS chemicals, but it only works well when there’s sufficient carbon volume and contact time in the tank as water flows through. For Chatham homes that means a full-size tank-based or backwashing GAC unit is generally more effective than small inline cartridges, and correct sizing helps the media last longer between services.
A GAC whole-house filter is installed on the main water line so it treats water used for bathing, cooking, laundry and more across the entire house. These systems are usually paired with a sediment prefilter to protect the carbon bed from clogging and channeling. For contaminants like 4:2 FTS, routine maintenance is as important as the initial installation because exhausted carbon can’t continue to adsorb PFAS. Mr. Pure Water can help Chatham homeowners choose a carbon system matched to their household flow and local conditions for reliable, house-wide protection.
