A disposable mask that includes a filter media capable of filtering particles of a size appropriate for its purposes, while providing excellent breathability. The mask is formed from multiple layers of filtration material having the general configuration of a trapezoid. 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.
