Abstract: |
A disposable mask that includes a filter body capable of filtering particles of a size appropriate for its purposes, while providing excellent breathability. An optically clear visor may be attached to opposite ends of the filter body to protect a wearer's eyes and face from liquid splash or spray. The filter body is formed from multiple layers of filtration material having the general configuration of a trapezoid. A darkened strip of material may be disposed on the exterior of the filter body adjacent to the visor to reduce glare and reflections by the visor. The mask is secured by straps to the head of a wearer. The straps are arranged to be approximately coextensive with a line extending from the edges which define the opening of the mask so that the edges are pulled into tight sealing engagement with the face of the wearer.
