Abstract: The technology disclosed herein relates to filter assemblies and methods of making filter assemblies. One filter assembly has a first sheet of filter media having a first perimeter region and a second sheet of filter media having a second perimeter region. The first perimeter region and the second perimeter region are bonded in a rim region. A plurality of adsorbent beads are disposed between the first sheet of filter media and the second sheet of filter media, and a substantial portion of the plurality of adsorbent beads are unbonded. Other embodiments are also described.

Abstract: A filter assembly for use in an electronics enclosure is disclosed herein. The filter assembly has an inner assembly having a filter material comprising fibrous media and a containment assembly having a first containment layer and a second containment layer. The containment assembly defines an outer perimeter and the first containment layer and a second containment layer are bonded along the outer perimeter in an outer weld area to encapsulate the inner assembly. The outer weld area extends between the outer perimeter and an interior perimeter. The inner assembly defines an inner assembly perimeter that is within the outer perimeter of the containment assembly.

Abstract: The present disclosure provides styrene/acrylonitrile fine fibers, filter media including styrene/acrylonitrile fine fibers, a recirculation filter including a styrene/acrylonitrile fine fiber or filter media, and methods.

Abstract: An article and method for degrading volatile organic compounds in an electronic enclosure is disclosed. The method comprises providing a substrate, such as a scrim material, and applying a catalyst to the substrate. The catalyst typically includes a base metal. The substrate and catalyst material are placed into a disk drive (or other electronic) enclosure where they help in degradation of organic compounds, in particular volatile organic compounds. In certain implementations the base metal is selected from the group of manganese, vanadium, nickel, copper, cobalt, chromium, iron, or combinations thereof.

Abstract: A process for separating the components of a gas mixture, including a sterilant gas and a diluent gas is disclosed. The gas mixture is fed to a membrane separation unit within which a perm-selective membrane is located which allows migration of diluent gas and sterilant gas at different rates. Both sterilant-rich and diluent-rich gas streams are withdrawn from the membrane separation unit and optionally recovered or further processed to a less hazardous compound. The process may be utilized to separate and treat the constituents of the exhaust gases from a chemical sterilization process of which the common components are olefin oxides such as ethylene oxide as a sterilant and chlorofluorocarbons (freon) such as dichlorodifluoromethane (CFC-1) as a diluent.
