    Many chemicals in drinking water can be removed with small activated-carbon filters.

    What are they? Units that drip into a pitcher, mount on the tap or install under the sink. These point-of-use filters remove many organic compounds, a wide class of carbon-containing chemicals that include pesticides and solvents.

    Do they work on PFCs? Preliminary testing by the Minnesota Health Department suggest small filters remove low levels of PFBA, a 3M film-coating chemical found in groundwater in the southeastern metro area. Further testing of filters is planned.
