ABSTRACT:
A self propelled moving-filter beverage maker includes an invertible housing having an elongate chamber, a cover at one end removably sealingly engaged with the housing for enabling the introduction and removal of liquid, and a separate non-neutral density filter free to move longitudinally in the chamber; the filter has a cross-section conforming to that of the chamber to minimize liquid bypass and has perforations at its longitudinal ends to accommodate liquid flow through the filter as the filter moves through the liquid each time the housing is inverted.
