摘要:
An earless filter mask includes an inner fabric layer, a filter layer, an outer fabric layer, a plurality of buttons, an exhalation valve, and a conforming band. The conforming band is sewn into an upper and a lower edge of the mask through in-seam sleeves with a first exposed portion extending beyond a first tapered end of the mask and a second exposed portion extending beyond a second tapered end of the mask. The conforming band conforms the mask to a shape of a wearer's face and a first tapered end of the mask is removably connected to a second tapered end of the mask at a nape of the wearer's neck.
