Including filter system and high-performance Methylene Chloride filter.
Methylene chloride is a volatile organic chemical that can show up in water supplies; you may also see it named dichloromethane on lab reports. It’s commonly used in industrial solvents and can enter drinking water when those solvents are handled, stored, or disposed of improperly. Because methylene chloride evaporates readily, potential exposure can come from more than just drinking — it can off-gas into the air from water during everyday activities when present at higher concentrations.
At low levels, methylene chloride usually isn’t detectable by taste, smell, or sight, so most Gritney homeowners learn about it only after water testing, particularly VOC screening. Unlike minerals that cause hardness or staining, this chemical won’t show the usual signs like scale, so testing is the reliable way to confirm its presence. The practical next step is a clear test of your water and a decision about whether point-of-use filters or a whole-house solution best fits your household’s needs.
The most common and effective single filter for reducing methylene chloride in household water is an activated carbon filter formulated for VOC removal. Quality carbon media adsorbs solvents such as methylene chloride (dichloromethane) as water flows through, lowering what reaches faucets and showers. Because VOCs can affect many uses around the home, many Gritney families prefer an entry-point whole-house carbon system so treated water reaches sinks, showers, laundry, and appliances consistently.
Not all carbon systems perform the same for VOCs, so matching carbon type, contact time, and flow capacity to your household needs is important. An entry-point activated carbon unit offers a centralized option for Gritney homes without installing multiple under-sink units. Mr. Pure Water can help you pick a whole-house carbon setup tuned for VOC reduction, including dichloromethane, based on your water test results and how your family uses water.
