ABSTRACT:
A disposable coffeemaker filter includes a flexible porous disposable filter bag for use in brewing coffee and a drawstring slidably threaded about a top perimeter edge of the filter bag. The drawstring can be pulled to draw the filter bag from an expanded open condition for brewing coffee to a collapsed closed condition for containing the wet used coffee grounds. The drawstring thereby enables the removal and disposal of the filter bag from the basket of a coffeemaker without spilling the coffee grounds from the filter bag.
