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 leach into aquifers. Because it readily evaporates, any contaminant in water can also move into the air during showers, laundry, or dishwashing — affecting both what you drink and what you breathe inside the home. It usually can’t be detected by taste, smell, or sight, so testing is the reliable way to know whether it’s present. If testing shows elevated levels, many Portland homeowners choose to treat the water at the point where it enters the house to protect indoor water use.
VOCs like 1,1-dichloroethylene are tracked in tiny concentrations and can vary over time, so clear-looking water isn’t a guarantee of safety. Families in Portland often prefer reducing exposure across everyday uses — cooking, brushing teeth, and bathing — rather than limiting treatment to a single faucet. A whole-house system delivers treated water to bathrooms, the kitchen, and appliances, giving a single consistent solution for the entire home and helping limit volatilization inside living spaces.
To reduce 1,1-dichloroethylene, the most effective single-filter whole-house choice is a granular activated carbon (GAC) system. GAC works by adsorbing many VOCs as water passes through the carbon media, removing contaminants before water reaches your showers, sinks, and household appliances. Installed as a point-of-entry unit for Portland homes, this approach addresses both ingestion risk and everyday uses where VOCs could off-gas into your indoor air.
Sizing the GAC tank correctly is important because sufficient contact time with the carbon is key for VOC removal, and the system should match your home’s flow rate and typical water use. Carbon media will eventually become exhausted and needs periodic replacement or re-bedding to maintain performance. Adding prefiltration helps protect the carbon bed from sediment that could shorten its life or increase pressure loss. Mr. Pure Water in Portland can help you choose and size a whole-house carbon setup tailored to your home and focused on reliably lowering 1,1-dichloroethylene.
