<p>The present invention relates to a dustproof mask with improved filterability and sealability, in which contact surfaces of upper, side, and lower parts of an inner surface of the dustproof mask are brought into close contact with a user′s body to prevent a polluted external air from being inhaled and thus an air inhaling through the dustproof mask is performed through only a surface where a user′s nose is located, thereby enhancing filtering and sealing functions of the dustproof mask. The dustproof mask with improved filterability and sealability according to the present invention includes a nose covering pad (10) covering a nose area and a mouth covering pad (20) to which the nose covering pad (10) is attached, wherein a partial-welded part (21) of which portions of both ends are horizontally ultrasonic-welded is formed on a lower part of the mouth covering pad (20), and a non-weld part (22) that is not welded is formed on a center part of the mouth covering pad (20). A chin contact part (23) covering a chin area is integrally formed with the mouth covering pad (20) under the partial weld part (21) and the non-weld part (22) and folded, and ear bands (24) are formed on both ends of the mouth covering pad (20).</p> |
