Abstract
An improved household coffee maker is disclosed, having a built-in water filter for removing water-borne contaminants. The water filter is disposed between the water reservoir and the heating coil, which heats the water and keeps the coffee carafe warm. An indicator disposed upon the cover of the coffee maker signals when the water filter has become saturated with contaminants and requires replacement or cleaning.
