  • Filter media comprising fibers including charged particles
    Patent number: 10384156
    Abstract: Filter media, including those suitable for hydraulic and/or other applications, and related filter elements and methods associated therewith, are provided. In some embodiments, a filter media described herein may include a layer (e.g., a non-woven layer) comprising a blend of glass fibers and polymeric fibers. The polymeric fibers may comprise a plurality of charged particles at least partially embedded within the polymeric fibers. In some embodiments, the layer comprising the fiber blend may result in an increased air permeability, dust holding capacity, and/or hydraulic gamma (a high ratio of air permeability to efficiency), as compared to filter media that do not include such charged particles.
    Type: Grant
