Including filter system and high-performance 1,1,1-Trichloroethane filter.
1,1,1-Trichloroethane is a synthetic solvent that can enter drinking water when industrial degreasers or related chemicals make their way into groundwater. As a volatile organic compound (VOC), it can affect not only drinking water but also water used for cooking, bathing, and cleaning. It may not alter water’s appearance, and any smell can be subtle, so visual checks aren’t reliable. That’s why many Cox homeowners choose to have their water tested to know whether this contaminant or other VOCs are present.
If testing shows 1,1,1-trichloroethane above recommended guidelines, treating the water where it enters the house is a common choice for homeowners in Cox. A whole-house system protects every faucet and appliance—bathrooms, laundry, and kitchen—rather than only the kitchen sink. This approach reduces routine exposure from everyday water use without asking you to change how you use water, and the right system targets VOCs while maintaining consistent pressure and flow throughout the home.
To lower 1,1,1-trichloroethane in household water, the most effective single option is a high-quality activated carbon filter formulated for VOC removal. Activated carbon removes many solvent-type contaminants by adsorption as water passes through the media. For whole-house protection this is usually built as a large carbon tank rather than a small cartridge so there’s enough contact time to handle the home’s full flow. Properly sized whole-home carbon systems treat both hot and cold water uses across the house.
Because 1,1,1-trichloroethane is a VOC, performance comes down to the carbon’s quality, how much media is installed, and the flow rate through the tank. A whole-house activated carbon filter for a Cox home should be sized to your household’s demand so water moves slowly enough for effective adsorption. Carbon does have a limited capacity and needs periodic replacement when it becomes exhausted.
