  • FILTER MEDIA WITH IMPROVED CONDUCTIVITY
    Publication number: 20160166960
    Abstract: Filter media are provided having improved conductivity to enhance filtration efficiency and/or dissipate static charge, and methods for making the same. In one exemplary embodiment, the filter media can include a filtration substrate, and at least one conductive coating disposed on at least a portion of the filtration substrate. In use, the conductive coating is coupled to an energy source and it is effective to emit ions when energy is delivered thereto to increase the efficiency of the filtration substrate and/or to dissipate or eliminate static charge generated during filtration.
    Type: Application
    Filed: November 11, 2015
    Publication date: June 16, 2016
    Applicant: Hollingsworth & Vose Company
    Inventors: Wai Ming Choi, Karin N. Soper
