Abstract

See full text

An earless filter mask includes an inner fabric layer, a first filter layer, a second filter layer, an outer fabric layer, an elastic material, and an exhalation valve. The inner fabric layer, the first filter layer, the second filter layer, and the outer fabric layer are stacked and aligned, the elastic material is folded over an edge of the layers, and sewn together along the edge. The elastic material 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 by a closure device that sits at the nape of the wearer's neck.
