Abstract: A respirator mask. The respirator mask has a filter that extends around at least a portion of the perimeter of the mask itself, leaving a central area that coincides with the position of the wearer's mouth unobstructed. A front panel of the mask may be transparent over at least the central area in order to allow the mouth to be seen while the mask is worn. The filter may be a pleated particulate filter, a chemical/gas filter, or a filter of mixed type. The front panel may also include other features, like a port for a drinking straw. The respirator mask may include headgear.
