Abstract:
A fluid filter is preferably constructed from a relatively thick batting of high loft, non-woven, fluid permeable fibrous material. The filter batting is then passed through a manufacturing device, which slices the batting in the vertical as to create two continuous filter batts from the parent filter batt. The slicing also creates a relatively deep V-shaped zig zag or waveform pattern in the anterior filter surfaces of the top and bottom of the batt. The top half deep V-shaped zigzag patterns peaks and valleys correspond or line up with the bottom half's valleys and peaks since the waveform landscape of the first child batt is essentially a negative impression of the second child batt. Accordingly, the patterns nest within one another. When separated, the two children batts each comprise a waveform landscape for dynamically directing fluid streams from the anterior filter surface to the posterior filter surface.
