Including filter system and high-performance 4:2 FTS filter.
4:2 FTS is a member of the PFAS family that can travel through groundwater and surface water, and homeowners most commonly hear about it from a utility notice, a private well test, or during a real estate inspection. You won’t detect 4:2 FTS by smell or taste, but many families in Runnymede choose to limit exposure in their drinking and cooking water and feel more confident about bathing and laundry. The first step is picking treatment designed for PFAS reduction rather than just sediment, softening, or basic taste improvement.
Because 4:2 FTS belongs to the broader group of fluorinated compounds, it’s often mentioned alongside other PFAS when testing flags a concern. Standard carbon pitchers, water softeners, and basic sediment cartridges don’t reliably remove PFAS on their own. For Runnymede homes—many of which in Florida deal with mineral scale and occasional well-water issues—the most dependable strategy is to treat water at the main line so every tap and appliance is protected instead of relying solely on an under-sink filter.
The single most effective whole-house option for reducing 4:2 FTS is a high-capacity granular activated carbon (GAC) system sized specifically for PFAS removal. Activated carbon can adsorb many PFAS compounds, but its effectiveness hinges on having enough carbon volume and sufficient contact time as water moves through the tank. That’s why a full-size tank-based or backwashing GAC unit generally works better for whole-home protection than small inline cartridges; proper sizing also helps the media last longer and perform more consistently between services.
A whole-house GAC filter is fitted on the main service line so it treats water for showers, sinks, laundry and kitchen use across your Runnymede home. These systems are typically paired with a prefilter to remove sediment and protect the carbon bed from clogging or channeling—important in Florida homes that may experience mineral scale or iron/sulfur in well supplies. Regular maintenance is key, because once carbon is exhausted it no longer adsorbs PFAS effectively. Mr. Pure Water can assess your home’s flow and water conditions and recommend the right carbon system for dependable, house-wide treatment.
