Abstract: A face mask and method of use are disclosed. A base of the face mask is placed around a lower region of the person's nose. A horizontal wall of the base is positioned under the person's nose and first and second bosses extending upwardly from the wall are positioned in the user's nostrils. Holes in the bosses allow the user to breathe through their nose. A filter assembly extends downwardly from the base and fits over the person's mouth and under their chin. An elastic frame on the filter assembly is press-sealed to the user's skin on either side of their mouth and under their chin. The horizontal wall prevents airflow between the environment and a space in front of the user's mouth. Exhaled and inhaled air is forced to pass through the filter assembly's filter, trapping infectious respiratory moisture droplets in the filter.
