ABSTRACT:
The specification discloses a filter stack in which a plurality of individual tapered frames with openings on their widest sides are alternatively aligned, with filter paper between adjacent frames, such that the openings in one frame face one way and those in the next adjacent frame face the other way. Parallel tongues projecting from one surface of the frames insure that filter paper will be clamped in place. Air leaks are eliminated by shrink-wrapping said stack of frames, except on the ends with openings, to firmly hold them together.
