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 show up in drinking water. In Betts homeowners often hear about concerns like this from a utility notice, a private well test, or during a real estate inspection. Because 4:2 FTS is colorless and odorless, many families choose to limit exposure and feel more confident about the water they use for drinking, cooking, and bathing. Tackling it usually means picking treatment designed for PFAS reduction rather than only addressing sediment, taste, or hardness.
Since 4:2 FTS belongs to the wider PFAS group, it’s commonly mentioned along with other fluorinated compounds when test results are reviewed. Typical carbon taste filters, standard water softeners, and basic sediment cartridges do not reliably remove PFAS on their own. For Betts homes, the most dependable strategy is whole-house treatment installed at the main line so every faucet and appliance is protected — avoiding the need to rely solely on an under-sink filter for peace of mind.
When the goal is reducing 4:2 FTS throughout a Betts house, the top whole-home choice is a high-capacity granular activated carbon (GAC) system sized and specified for PFAS removal. Activated carbon adsorbs many PFAS compounds, but its success depends 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 typically outperforms small inline cartridges for whole-house reduction; proper sizing also extends media life and keeps performance steady between services.
A whole-house GAC filter is mounted on your main water line so showers, sinks, laundry and kitchen taps all receive filtered water. These systems are commonly paired with a sediment prefilter to prevent clogging and channeling in the carbon bed. For chemicals like 4:2 FTS, regular maintenance is essential because spent carbon can no longer adsorb PFAS effectively. Mr. Pure Water can help Betts homeowners pick the right carbon capacity and flow configuration for their property’s water use and conditions to ensure reliable, house-wide treatment.
