Abstract: A personal protective mask includes a mask body having an expandable section that is positioned between the top and bottom ends of the mask. An adhesive material is positioned on the inside surface of the mask along the outer periphery. The adhesive includes skin safe adhesive for creating an air tight seal between the mask and the face of a wearer. The mask includes a nose clip, a sweat band and at least one headband. The mask is constructed in accordance with N95 standards, and the expandable section transitions between a contracted and expanded state, to conform to the movements of the user's jaw. The expandable section includes two folds and a middle section. The folds move linearly about each other so as to prevent deformation of the mask outward from the user's face.
