The dustproof mask for nose includes a clamping unit having two wings and surrounding the nasal septum (the septum of the nose) of a user; connection portions installed at tips of the two wings; and filters installed at the connection portions. In the dustproof mask for nose, the filters (10) have a hemispheric shape, nipple-shaped connectors, which are formed at the connection portions, are inserted into connection holes, which are formed through the central areas of the filters, and fixing protrusions for firmly holding the nasal septum are formed on the wings of the clamping unit.
