Pattern coated filter and method

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 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 region, wherein the first perimeter region and the third perimeter region are bonded. The base layer, second layer, and third layer are substantially coextensive. 本技术总体上涉及种过滤组件。所述过滤组件具有第层，所述第层具有限定了第周边区域和在所述第周边区域中央的区域的基础层。第粘合剂被布置在所述第层的第表面上基本上在所述中央区域内，并且第吸附剂珠粒联接到所述第粘合剂上。第二层具有第过滤材料片材，所述第过滤材料片材具有第二周边区域，其中，所述第周边区域与所述第二周边区域相结合。第三层具有第二过滤材料片材，所述第二过滤材料片材具有第三周边区域，其中，所述第周边区域与所述第三周边区域相结合。所述基础层、第二层、以及第三层是基本上同延的。
