Including filter system and high-performance 4:2 FTS filter.
4:2 FTS is one of the PFAS chemicals that can travel through soils and groundwater and show up in drinking water. City Point homeowners usually first hear about it from a utility notice, a private well test, or a water-quality report during a home sale. Because 4:2 FTS is invisible and tasteless, many families prefer to limit exposure and feel confident about the water they use for cooking, drinking, and bathing. In our humid subtropical part of Florida, it’s important to choose treatment made for PFAS reduction rather than relying only on sediment or basic taste filters.
Since 4:2 FTS belongs to the wider PFAS group, lab results or conversations about contamination often lump it together with other fluorinated compounds. Typical carbon taste filters, water softeners, and sediment cartridges aren’t guaranteed to remove PFAS reliably. For City Point homes—where hard water and mineral buildup are common—treating water at the main service entry ensures every faucet and appliance is protected. A whole-house system gives broader peace of mind than relying only on a single under-sink unit.
To reduce 4:2 FTS across your whole house, the top-performing option is a high-capacity granular activated carbon (GAC) system sized specifically for PFAS treatment. Activated carbon can adsorb many PFAS compounds, but efficacy depends on having enough carbon volume and sufficient contact time as water passes through the tank. For meaningful whole-home reduction in City Point, a full-size tank-based or backwashing GAC unit will usually outperform small inline cartridges. Correct sizing also helps the media last longer and perform consistently between services.
A whole-house GAC unit is plumbed on the main line so it treats water for showers, sinks, laundry, and kitchen use across your City Point home. These systems are commonly paired with a sediment prefilter to protect the carbon bed from clogging and channeling—important in coastal Florida areas where mineral-rich, hard water can increase scale risk. Because spent carbon can no longer adsorb PFAS, regular maintenance matters as much as proper installation. Mr. Pure Water can assess your home’s flow requirements and water conditions to recommend the right carbon system for dependable, house-wide treatment.
