Including filter system and high-performance 4:2 FTS filter.
4:2 FTS is a PFAS compound that can travel through the environment and sometimes shows up in drinking water. In Lakewood many homeowners first hear about it from a utility notice, a real estate or private well test, or news about PFAS in the region. Because you can’t see or taste 4:2 FTS, people often want added assurance that the water they use for cooking, drinking and bathing is lower in these persistent chemicals. For Lakewood households that means looking for treatments aimed at PFAS reduction rather than only sediment, chlorine, or taste improvements.
Since 4:2 FTS belongs to the wider PFAS family, it’s commonly mentioned alongside other fluorinated compounds even when it’s the one detected on a report. Typical carbon taste filters, water softeners and sediment cartridges won’t reliably remove PFAS on their own. The most dependable strategy for Lakewood homes is whole-house treatment at the main water line so every tap and appliance is covered—rather than depending solely on a single under-sink filter for peace of mind.
To reduce 4:2 FTS throughout the house, the single most effective whole-home option is a high-capacity granular activated carbon (GAC) system sized and specified for PFAS removal. Activated carbon can adsorb many PFAS compounds, but success depends on having sufficient carbon volume and contact time as Lakewood water moves through the tank. That’s why full-size tank-based or backwashing GAC units are usually a better choice than small inline cartridges when you want meaningful, house-wide reduction. Correct sizing also extends media life and helps the system perform consistently between services.
A whole-house GAC filter is mounted on the main supply so every shower, sink, laundry load and kitchen tap receives treated water. These systems are commonly installed with a prefilter to remove sediment and protect the carbon bed from clogging and channeling. For contaminants like 4:2 FTS, regular maintenance matters because spent carbon can no longer adsorb PFAS effectively. Mr. Pure Water in Lakewood can evaluate your home’s flow requirements and water conditions and recommend the right carbon system so you get dependable, house-wide treatment.
