An outer pressing respirator mask includes a fastening device (8) and a precoat (4) of the respirator. It includes a flexible component which is deformed when being tightly appressed to a human face, to press the precoat (4) of the respirator mask which is close to the skin against the circumference of the area including a nostril or a snoot, so as to separate the area from the external environment by the precoat (4) of the respirator.
