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 groundwater and sometimes end up in household supplies. In Perkins many homeowners first hear about these contaminants from a water utility notice, a private well test, or during a real estate inspection. Because 4:2 FTS has no taste or odor, families often choose treatment to lower exposure and gain confidence in water used for drinking, cooking and bathing. Addressing it effectively means picking systems designed for PFAS reduction rather than relying only on basic sediment filters or taste-and-odor cartridges.
Since 4:2 FTS belongs to the wider PFAS group, it frequently appears alongside other fluorinated compounds on lab reports even when it’s the specific compound detected. Common whole-house appliances like water softeners, simple carbon pitcher filters, and sediment cartridges don’t consistently remove PFAS. For Perkins homes, the most dependable strategy is treating water at the point it enters the house so every tap and appliance is protected, rather than depending solely on a single under-sink filter for reassurance.
To reduce 4:2 FTS throughout a home, the best whole-house option is a high-capacity granular activated carbon (GAC) system sized and built specifically for PFAS removal. Activated carbon can adsorb many PFAS compounds, but real-world performance requires sufficient carbon volume and adequate contact time as water passes through the tank. That’s why full-size, tank-based or backwashing GAC units are generally more effective for whole-home reduction than small inline cartridges. Correct sizing also prolongs media life and keeps performance steady between servicing.
A whole-house GAC unit is installed on the main water line so showers, sinks, laundry and kitchen fixtures all receive treated water. These systems are commonly paired with a sediment prefilter to prevent channeling and protect the carbon bed. For contaminants like 4:2 FTS, routine maintenance is critical because spent carbon cannot adsorb PFAS effectively. At Mr. Pure Water in Perkins we help select the right GAC system for your home’s flow requirements and water conditions so you get reliable, house-wide PFAS reduction.
