  • Publication number: 20240082763
    Abstract: Filter media and filters, such as air filters, residential air filters, commercial air filters, face masks, gas turbine and compressor air intake filters, panel filters, and the like, are provided that comprise a plurality of fibers with a silicone-based coating. The silicone-based coating comprises a silicone compound at least about two percent by weight of the coating. The silicone-based coating may include a reactive silicone macroemulsion and a surfactant. The silicone-based coating increases the efficiency of the filter at capturing contaminants, particularly contaminants in the E2 and E3 particle group range, without compromising other important characteristics of the filters, such as cost, longevity, dust holding capacity, and the pressure drop or air permeability of the filter.

  • Publication number: 20230323576
    Abstract: Systems, devices and methods are provided for producing fibrous materials and products, such as filters. A system comprises a first device for generating one or more fiber stream(s), and a second device for isolating nanoparticles within a gaseous medium. The second device forms the nanoparticles into a stream and feeds this stream into the fiber streams to form the fibrous material. This distributes the nanoparticles more uniformly throughout the fibrous material. In addition, the nanoparticles increase the overall surface area within the material, which, in certain applications, increases its filtration efficiency and allows for the capture of submicron contaminants without significantly compromising other factors, such as pressure drop through the filter. Filters produced with these systems and methods are capable of withstanding rigorous conditioning, which allows the filter to achieve substantially the same level of filtration performance throughout the lifetime of the filter.

  • Publication number: 20230321575
    Abstract: Filter media and filters, such as air filters, face masks, gas turbine and compressor air intake filters, panel filters and the like, are provided that include high linear density fibers and nanoparticles dispersed throughout at least a portion of the filter media. A filter includes a filter media comprising a substrate of fibers having a linear density of greater than about 3 denier, and nanoparticles disposed within the substrate. The larger linear density fibers provide more open space or pores within the filter media, allowing for a greater density of nanoparticles to be dispersed therein. This improves the overall efficiency of the filter. The three-dimensional distribution of nanoparticles within the filter also provides resistance against complete blockage of a particular portion of the filter, thereby reducing the overall pressure drop across the filter.

  • Publication number: 20230321584
    Abstract: Filter media and filters, such as air filters, face masks, gas turbine and compressor air intake filters, panel filters and the like, are provided that include nanoparticles dispersed throughout at least a portion of the filter media. A filter media comprises a fiber substrate with a first surface and an opposing second surface. The filter media includes nanoparticles disposed within the fiber substrate at least between the first and second surfaces such that an area density of the nanoparticles decreases from the first surface towards the second surface. This density gradient formed by the nanoparticles through at least a portion of the substrate improves the performance characteristics of the filter. The nanoparticles increase the overall surface area within the fiber substrate, which may increase its filtration efficiency and allows for the capture of submicron contaminants without significantly compromising other factors, such as pressure drop or air flow through the filter.

  • Publication number: 20230321572
    Abstract: Systems, devices and methods are provided for separating and/or isolating individual nanoparticles from groups or clusters of nanofibers within a gaseous medium. The system comprises a housing configured to contain the groups of nanofibers, and a pump coupled to the housing. The system further includes one or more passages coupled to the pump and a gaseous medium within the passages. The pump is configured to propel the nanofibers through, or with, the gaseous medium against one or more surface(s) within the passages at a sufficient velocity and/or momentum to open up or separate, the groups of nanofibers into individual nanoparticles. Isolating individual nanoparticles in a gaseous medium and then dispersing them into a substrate or a fluid stream to form a product allows the nanoparticles to be distributed more uniformly and “in depth” throughout the product.

  • Publication number: 20230321569
    Abstract: Filter media and filters, such as air filters, face masks, gas turbine and compressor air intake filters, panel filters and the like, are provided that capture submicron particles with both electrostatic forces and the utilization of nanoparticles within the filter media. A filtration media includes a substrate comprising fibers and nanoparticles disposed within the substrate. At least one of the fibers or the nanoparticles are electrostatically charged. The electrostatic charge effectively captures submicron particles during at least the initial use of the filter. The nanoparticles ensure that the efficiency of the filter remains high even after the electrostatic charge starts to decay over time. In addition, the bond between the fibers and the nanoparticles may be enhanced by the electrostatic charge, which allows the nanoparticles to be dispersed in depth throughout the filter media.

  • Publication number: 20230323575
    Abstract: Nonwoven materials and products comprising nonwoven materials are provided that include a substrate comprising fibers and nanoparticles incorporated into at least a portion of the substrate. A nonwoven material comprises a substrate comprising fibers and having a first surface and an opposing second surface, and nanoparticles disposed within the substrate at least between the first and second surfaces. The density of the nanoparticles decreases from the first surface towards the second surface, or a higher density of nanoparticles is disposed on the two surfaces as compared to the middle section of the substrate. This density gradient formed by the nanoparticles improves the performance characteristics of the material for a number of different applications.
