  • Publication number: 20210106937
    Abstract: Various embodiments of a filter cartridge are disclosed. The filter cartridge includes a first filter media layer having first and second major surfaces, a second filter media layer having first and second major surfaces, and a plenum disposed between the first and second filter media layers. The filter cartridge further includes functional material disposed on the first major surface of each of the first and second filter media layers within a filter region of the filter cartridge, where the functional material includes active particles disposed on an adhesive layer; and a perimeter seal region that defines at least a portion of a perimeter of the filter cartridge, where at least the first and second filter media layers are connected together in the perimeter seal region. The functional material is not disposed in at least a portion of the perimeter seal region.
