Including filter system and high-performance 1,1-Dichloroethylene filter.
1,1-dichloroethylene is a volatile organic compound (VOC) that can enter groundwater when certain industrial solvents or related chemicals contaminate the source. Because it readily evaporates, it can move from water into the air during showers, laundry and dishwashing, potentially affecting indoor air as well as drinking water. It’s usually not detectable by taste, smell or sight, so testing is the reliable way to know whether it’s present. If your Delta water test shows elevated levels, treating the water where it enters the house is a sensible next step.
VOCs such as 1,1-dichloroethylene can be concerning even when water appears clear, since they’re measured at very low concentrations and can fluctuate over time. Many Delta families choose to limit exposure during everyday activities—cooking, brushing teeth and bathing—rather than addressing just a single tap. A whole-house solution delivers consistent treated water to bathrooms, the kitchen and appliances so you have one system protecting the whole home’s routine.
The most effective single-filter option for reducing 1,1-dichloroethylene is a whole-house granular activated carbon (GAC) filter. GAC media adsorbs many VOCs as water flows through the carbon bed, removing contaminants before water reaches sinks, showers and appliances. Installed at the point of entry, this type of system helps limit both ingestion and the household volatilization that can occur during normal use in Delta homes.
Proper sizing of a GAC tank is important because contact time with the carbon affects VOC removal, so the system needs to match your household flow rates and water use. Carbon media will become exhausted over time, so routine replacement or re-bedding is necessary to maintain performance. Adding prefiltration protects the carbon from sediment that can reduce efficiency and raise pressure loss. Mr. Pure Water can work with Delta homeowners to pick a whole-house carbon setup tailored to their home and focused on lowering 1,1-dichloroethylene reliably.
