Including filter system and high-performance 4:2 FTS filter.
4:2 FTS is one of the PFAS chemicals that can travel through soil and water and sometimes appears on utility notices, private well tests, or real estate water reports. You won’t be able to see or taste 4:2 FTS, but many Salem homeowners prefer to reduce their family’s contact with it in drinking, cooking, and bathing water. Starting with treatment meant for PFAS — not just sediment or basic taste filters — is the usual first step toward greater confidence in your home’s plumbing.
Because 4:2 FTS is grouped with other fluorinated PFAS, it’s often mentioned alongside similar compounds on lab reports. Typical carbon taste filters, water softeners, and sediment cartridges aren’t guaranteed to remove PFAS consistently. For Salem homes, the most dependable strategy is to treat water where it enters the house so showers, faucets, and appliances are all covered instead of relying on a single under-sink filter for peace of mind.
To reduce 4:2 FTS throughout a house, the best single whole-home option is a high-capacity granular activated carbon (GAC) system sized and specified for PFAS removal. Activated carbon adsorbs many PFAS compounds, but its effectiveness relies on having sufficient carbon volume and enough contact time as Salem’s water moves through the tank. That’s why a full-size tank-based or backwashing GAC unit is usually preferable to small inline cartridges when the goal is meaningful, home-wide reduction, and why proper sizing extends media life between services.
A whole-house GAC filter is fitted on the main service line so water used for showers, laundry, and cooking all gets treated. These systems are commonly paired with a sediment prefilter to protect the carbon bed from clogging and channeling. For contaminants like 4:2 FTS, regular maintenance matters — exhausted carbon won’t adsorb PFAS effectively. Mr. Pure Water can assess your Salem home’s flow requirements and water conditions and help select and size the right carbon system for reliable, house-wide protection.
