Abstract
Abstract for filtering drinking water which includes a lower non-porous container to receive the filtrate. An upper filter vessel closed at its lower end by a high density ceramic filter is stacked in nested relationship to the lower container. When water containing contaminants and pollutants is poured into the filter vessel, it drips through the ceramic filter under gravitational forces and is stored in the lower receptacle.
