  • Publication number: 20220168596
    Abstract: A respirator includes a frame, a filter layer, and a face seal member. The frame has an outer side and an inner side. The frame defines an opening therethrough. The filter layer is mounted to the outer side of the frame and covers the opening of the frame. The filter layer is configured to prohibit permeation of aerosol, gas, and/or vapor contaminants therethrough. The face seal member is mounted to the inner side of the frame. The face seal member includes a seal contact area configured to engage a facial surface of a wearer. The face seal member incorporates a phase change material therein. The phase change material is configured to provide localized cooling by absorbing heat emitted by the wearer.

  • Patent number: 10537755
    Abstract: Thermally deformable face seals and respirators including such face seals. The thermally deformable face seal structures comprise composite phase change materials that mold to the face of a user to provide a personalized but one-size-fits-all facial fit having excellent shape retention after use and long term durability. The phase change material is applied onto a base component to cover all or substantially all of the surface area of the base component and adapts to the face of the user to provide a secure, leak-free seal.

  • Patent number: 8979985
    Abstract: A conformal filter is disclosed having a plurality of sorbent beds oriented perpendicular to an inner side surface of the filter which conforms to an adjacent surface, such as a wearer's face when attached to a respirator. The inner side of the filter may approximate the curved shape of an interfacing surface. Because the sorbent beds are oriented perpendicular to the inner side surface, a conformal configuration can be achieved without bending the sorbent beds and while keeping constant bed residence time throughout the entire cross-sectional area of the air flow, thus enforcing even air distribution. Reduced bed depth is also achieved through this configuration which consequently reduces the overall pressure drop through the filter. Other embodiments are described and claimed.
