Abstract
Face mask devices, systems, and methods of use include a frame that holds a suitable filter material, including a face mask, over the user's face to form a seal and prevent unfiltered air from being inhaled through the nose or mouth of the user without first passing through the filter material. The frame is removably attached over the users face by, for example, adjustable straps. The frame may be adjustable in size to be suitable for use on user's having different facial sizes, shapes, and/or geometries.
