Including filter system and high-performance 4:2 FTS filter.
4:2 FTS is a member of the PFAS family that can move through the environment and sometimes appear in drinking water. Homeowners in Sears may first hear about it from a utility notice, a private well test, or a real estate inspection. Although you won’t taste or see 4:2 FTS, many families prefer to limit exposure and feel secure about water used for cooking, drinking, and bathing. Tackling it starts with selecting treatment made for PFAS removal rather than relying on basic sediment or taste-only filters.
Because 4:2 FTS belongs to the broader PFAS group, reports may group it with other fluorinated compounds even when 4:2 FTS is the one noted. Typical carbon pitchers, water softeners, and sediment cartridges don’t consistently remove PFAS. For Sears homeowners, the most dependable solution is whole-house treatment installed where water enters your property so every tap and appliance is covered — not just a single under-sink filter.
The single most effective whole-home option for reducing 4:2 FTS is a high-capacity granular activated carbon (GAC) system sized and configured for PFAS removal. Activated carbon can adsorb many PFAS chemicals, but success depends on sufficient carbon volume and enough contact time as water passes through the tank. That’s why a full-size tank-based or backwashing GAC unit is usually a better choice than small inline cartridges when you want meaningful, house-wide reduction; correct sizing also helps the media last longer and perform reliably between services.
A whole-house GAC filter is placed on the main water line to treat water for showers, sinks, laundry and kitchen use in every room of a Sears home. These systems are commonly paired with a sediment prefilter to protect the carbon bed from clogging and channeling — an important consideration in Central Florida’s hard, mineral-rich groundwater. For contaminants like 4:2 FTS, regular maintenance is as important as proper installation because spent carbon won’t keep adsorbing PFAS. Mr. Pure Water can help size and match a carbon system to your home’s flow requirements and local water conditions so you get consistent, house-wide protection.
