Including filter system and high-performance 4:2 FTS filter.
4:2 FTS is a member of the PFAS family that can travel through soil and water, and homeowners most often hear about it from a utility notice, a private well test, or a real estate inspection. Because you can’t see or taste 4:2 FTS, many families in Koerber choose to take extra steps to limit their exposure and feel confident about the water they use for drinking, cooking, and bathing. Tackling it usually means picking treatment made for PFAS reduction rather than relying on basic sediment or taste-focused filters.
Since 4:2 FTS is discussed as part of the broader PFAS group, it’s often listed alongside other fluorinated compounds on reports. Typical carbon taste filters, water softeners, and sediment cartridges aren’t necessarily built to remove PFAS reliably. The most effective strategy for Koerber homes is whole-house treatment at the main incoming line so every faucet and appliance benefits, rather than depending solely on a single under-sink unit for peace of mind.
When the goal is whole-house reduction of 4:2 FTS, the top choice is a high-capacity granular activated carbon (GAC) system sized and specified for PFAS removal. Activated carbon can adsorb many PFAS chemicals, but how well it works relies on having sufficient carbon volume and enough contact time as water passes through the tank. For meaningful, home-wide treatment in Koerber, a full-size tank-based or backwashing GAC unit typically outperforms small inline cartridges, and correct sizing helps the media last and perform consistently between services.
A whole-house GAC unit is fitted on the main water line so showers, sinks, laundry and kitchen fixtures all receive treated water; it’s commonly used with a prefilter to remove sediment and protect the carbon bed from clogging. For contaminants like 4:2 FTS, routine maintenance matters as much as the initial install because spent carbon won’t keep adsorbing PFAS. Mr. Pure Water can assess your Koerber home’s flow needs and water conditions and recommend the right GAC system so you get consistent, house-wide protection.
