An apparatus for use with a coffee maker holds the grounds in a cylindrical configuration in the hot water stream for more uniform and efficient extraction. A thin-wall, right cylinder has a slotted lower edge. A thin-wall frustum of a cone also has a smaller diameter, slotted lower edge. Both lower edges are resilient and cooperate with one another to hold the central portion of a filter elastically therebetween. The peripheral portion of the filter is held securely in the annular space between cylinder and frustum. The slots in the cylinder also provid...
