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.
