The nose plug (1) lends itself well, owing to its conically arched shape, to insertion into the nostrils until it fits the wings of the nose. The main part (4) is hollow. Air-permeable screens (3, 5) are fitted at both ends. The cavity (6) can be filled (7) with various granules which are suitable for gas adsorption. People who are exposed to waste-gas areas can apply the nose plugs quickly and individually. <IMAGE>
