Including filter system and high-performance 1,1-Dichloroethylene filter.
1,1-Dichloroethylene is a volatile organic compound (VOC) that can enter drinking water when certain industrial solvents or related chemicals reach groundwater. Because it readily evaporates, it can move from water into the air inside your home during showers, dishwashing, or laundry — affecting more than just the water you drink. It often has no noticeable taste, smell, or appearance, so the only reliable way to know whether it’s present is through testing. If testing shows elevated levels, treating the water where it enters your Holley house is a practical next step.
VOCs such as 1,1-dichloroethylene are typically detected at very low concentrations that can change over time, so even clear water can warrant concern. Many Holley households choose to limit exposure for everyday uses like cooking, brushing teeth, and bathing rather than only treating one faucet. A point-of-entry, whole-house solution delivers treated water to bathrooms, the kitchen, and connected appliances so the whole home benefits from consistent protection.
The most effective single whole-house option for reducing 1,1-dichloroethylene is a granular activated carbon (GAC) filter installed at the point of entry. GAC media adsorbs many VOCs as water flows through, removing contaminants before they reach showers, sinks, or appliances. In Holley homes a properly configured GAC tank helps address both ingestion and the everyday volatilization that can occur during household activities.
Sizing the GAC tank correctly is important because removal depends on sufficient contact time, and the system should match your home’s flow rate and typical water use. Over time the carbon bed will become exhausted and will need scheduled replacement or re-bedding to maintain performance. Adding a sediment prefilter can protect the carbon from particulate that reduces efficiency and increases pressure drop. Mr. Pure Water can work with Holley homeowners to choose a whole-house carbon system sized for their property and aimed at lowering 1,1-dichloroethylene effectively.
