The inventive device includes a support ring positionable within a filter basket so as to capture an upper edge of a coffee filter between the ring and the basket. A plurality of vertical stanchions depend from the support ring for engaging a bottom of the basket to support the ring at a desired position therein. An adjustment assembly is provided for varying a diameter of the ring and each stanchion includes frangible notches permitting sizing of the stanchions to a desired height.
