Filter assembly for an enclosure

Abstract:

The technology disclosed herein relates to a filter assembly. The filter assembly has a double-sided adhesive layer having a first side and a second side and defining a filter opening. A first membrane extends over the filter opening and is directly coupled to the first side of the double-sided adhesive layer about the filter opening. An adsorbent element is directly coupled to the first membrane, where the adsorbent element and the first membrane are coextensive. A second membrane encapsulates the first membrane and the adsorbent element. The second membrane is directly coupled to the first side of the double-sided adhesive layer around the first membrane and adsorbent element.
