Abstract

An improved multi-layer face mask has at least one adhesive strip applied between the inner face cover layer and the intermediate filter layer. The adhesive strip is defined so as to extend across the filter body and is bounded on each longitudinal side by longitudinally extending regions that are free of adhesive. The adhesive strip may be disposed along a pleat formed in the face mask body. For example, the adhesive strip may have a width so as to extend between parallel fold lines of a pleat.
