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 industrial solvents or related chemicals reach groundwater. Because it readily evaporates, it can move from water into indoor air during showers, laundry or dishwashing — so exposure isn’t limited to what you drink. It usually can’t be seen, tasted, or smelled, which is why testing is the reliable way to know whether it’s in your supply. If testing in Duck Key or elsewhere in Monroe County shows elevated levels, addressing the issue where water enters your home is the most comprehensive step.
VOCs such as 1,1-dichloroethylene can be present in very low concentrations and fluctuate over time, even when water appears clear. Many Duck Key homeowners prefer reducing exposure across all household uses — cooking, brushing teeth, bathing — rather than treating only one tap. A whole-house solution delivers consistent treated water throughout bathrooms, the kitchen and to appliances, which is especially useful in Florida Keys homes where protecting plumbing and fixtures from hard water and airborne VOCs matters for daily living.
The most effective single-filter option for lowering 1,1-dichloroethylene at the point of entry is a whole-house granular activated carbon (GAC) system. GAC works by adsorbing many volatile organic compounds as water passes through the carbon media. When installed as a point-of-entry filter, it treats water before it reaches showers, sinks and appliances, helping reduce both ingestion and the chance that VOCs will volatilize into indoor air in your Duck Key home.
Sizing a GAC tank correctly is important because contact time with the carbon determines how effectively VOCs are removed, and the system should match your household flow and usage patterns. Carbon media eventually becomes exhausted and requires scheduled replacement or re-bedding to maintain performance. Adding prefiltration helps keep sediment out of the carbon bed, preserving efficiency and limiting pressure loss—useful in hard-water environments like the Florida Keys.
