Abstract

PATTERN COATED FILTER AND METHOD 5 The present technology is generally related to a filter assembly. The filter assembly has a first layer has a base layer defining a first perimeter region and a region central 10 to the first perimeter region. A first adhesive is disposed on a first surface of the first layer substantially within the central region, and first adsorbent beads are coupled to the first adhesive. A second layer has a first sheet of filter material having a second perimeter region, wherein the first perimeter region and the second perimeter region are bonded. A third layer has a second sheet of filter material having a third perimeter 15 region, wherein the first perimeter region and the third perimeter region are bonded. The base layer, second layer, and third layer are substantially coextensive. FIG. 2
