A coffee filter qualification system receives user-specified filter criteria relating to acceptable attributes for a plurality of apertures included in a liquid brewing filter. A light source illuminates the apertures of the liquid brewing filter and a machine vision camera images the apertures of the filter. A filter qualification information handling system (IHS) determines if the liquid brewing filter meets the predefined user-specified filter criteria. The filter qualification IHS accepts the liquid brewing filter if the filter meets the filter criteria, and otherwise rejects the filter. The filter criteria may include the total cumulative area of the apertures, individual aperture area, aperture count and aperture acircularity information.
