Including filter system and high-performance 4:2 FTS filter.
4:2 FTS is one of the PFAS family members that can travel through the environment and end up in water supplies. In Century homeowners typically encounter information about it from utility notices, a real estate water test, or a private-well sampling — even though you can’t see or taste the chemical. Many families in Century want to reduce their household exposure and be confident in the water they use for drinking, cooking, and bathing. Starting with treatment targeted at PFAS, rather than only sediment or taste issues, is the practical first step.
Because 4:2 FTS belongs to the broader group of fluorinated compounds, reports may list it alongside other PFAS even when it’s the specific concern. Typical carbon taste filters, water softeners, and sediment cartridges are not guaranteed to remove PFAS effectively. The most dependable strategy for Century homes is whole-house treatment at the point where water enters the property so every tap and appliance is protected. That approach avoids depending on a single under-sink filter for peace of mind across the whole house.
To reduce 4:2 FTS throughout a home, the most effective single whole-house option is a high-capacity granular activated carbon (GAC) system sized and configured specifically for PFAS removal. Activated carbon can adsorb many PFAS compounds, but its success hinges on having sufficient carbon volume and contact time as water moves through the tank. For meaningful, home-wide reduction in Century properties, a full-size tank-based or backwashing GAC unit is generally a better choice than small inline cartridges, and correct sizing helps the media perform reliably between services.
A whole-house GAC filter is fitted on the main supply line so showers, sinks, laundry and the kitchen receive treated water without needing separate point-of-use units. These systems are commonly paired with a prefilter to remove sediment and protect the carbon bed from clogging or channeling. For contaminants like 4:2 FTS, routine maintenance is as important as the initial installation because spent carbon will stop adsorbing PFAS. Mr. Pure Water can assess Century homes, recommend the right carbon capacity for your flow requirements, and keep the system tuned for consistent, house-wide treatment.
