Publication number: 20230330451Abstract: This disclosure describes filter media and mask filters and face mask systems including those filter media. In one aspect, the filter media includes a fibrous media including multi-component binder fibers, glass fibers, and microfibrillated cellulose fibers. In some aspects, the fibrous media further includes PET fibers. In another aspect, the filter media includes an electrostatically charged filter media, a fine fiber layer, and a scrim. In yet another aspect, the filter media includes two fine fiber layers, and two scrims. In additional aspects, the filter media includes bicomponent fibers, polyethylene terephthalate fibers, and microfibrillated cellulose fibers. In a further aspect, the filter media includes a support layer, a continuous fine fiber layer, and an efficiency layer. Combinations and composites of the filter media are also contemplated.Type: ApplicationFiled: April 2, 2021Publication date: October 19, 2023Inventors: Derek O. Jones, Joseph M. Block, Klenton T. Willis, Patricia A. Ignacio-de Leon, James P. Barsness, Dustin A. Zastera, William A. Osmer, Thomas M. Weik, Jacob C. Savstrom

Patent number: 10058807Abstract: The assemblies of the invention can comprise a fine fiber layer having dispersed within the fine fiber layer an active particulate material. Fluid that flows through the assemblies of the invention can have any material dispersed or dissolved in the fluid react with, be absorbed by, or adsorbed onto, the active particulate within the nanofiber layer. The structures of the invention can act simply as reactive, absorptive, or adsorptive layers with no filtration properties, or the structures of the invention can be assembled into filters that can filter particulate from a mobile fluid while simultaneously reacting, absorbing, or adsorbing materials from the mobile fluid.Type: GrantFiled: February 14, 2017Date of Patent: August 28, 2018Inventors: Andrew J. Dallas, William Lefei Ding, Jon D. Joriman, Dustin Zastera, James R. Giertz, Veli E. Kalayci, Hoo Y. Chung

Patent number: 9839870Abstract: A filter is includes a housing and at least first and second adsorbent materials within the housing. The second adsorbent material has different characteristic from the first adsorbent material and is in series with the first adsorbent material. When assembled, a labyrinth arrangement is located between a first port in the housing and the first adsorbent material such that gas travels between the first port and the first adsorbent material by passing through the labyrinth arrangement. A filtration system and methods for humidity control of a liquid tank head space uses a filter, including first and second adsorbent and a diffusion channel or labyrinth arrangement.Type: GrantFiled: October 14, 2016Date of Patent: December 12, 2017Assignee: Donaldson Company, Inc.Inventors: Dustin Zastera, Gregory L. Lavallee, Marty A. Barris

Publication number: 20170341057Abstract: The technology disclosed herein is directed to controlling humidity levels, such as the humidity level in an enclosed environment. The water isotherm of the adsorbent material is customized through the modification of the surface chemistry of the adsorbent. By modifying the surface chemistry of the adsorbent in various ways and to varying degrees, it is possible to customize the adsorbent properties to a range of different humidity levels. Such modification can enhance the adsorbing capacity and efficiency of the adsorbent, especially with regard to low molecular weight water-soluble compounds.Type: ApplicationFiled: July 11, 2017Publication date: November 30, 2017Inventors: Yehya A. Elsayed, Andrew J. Dallas, Jon D. Joriman, Dustin Zastera
