An improved nasal filter that is adapted to be inserted in the nasal passages of the nose and held therein by a clip applying tension on the septum walls. The filter includes a pair of unbrellalike structured cups each having an open base and covered outer side. The frame of said filter cups are formed from non-allergenic flexible plastics. From a common center cylinder, flexible limbs protrude radially, horizontal and vertically downward and are joined equally at the base and adhered to a soft flexible circular ring which maintains the round shape. The entire outer frame excluding said ring is clad with a thin porous filtering material suitable for filtering dust particles yet maintaining easy breathing. Within the common center cylinder is located a receiving round socket aperture which connects onto a round ball formed on the ends of the septum bridge clip. This type of connection allows the filter cup to align itself by tilting into position inside the nasal passages and allows the filter cup to be disposed of when saturated with dust particles. The said septum bridge is made from hard flat flexible plastics which is contoured to fit around the septum with arms extending upward and parallel bowed inward toward each other applying slight tension on the septum walls then angling outward and upward terminating with a round ball for interlockment within said common center cylinder socket apertures walls.
