The nose device has a conical portion with a distal end intended to be arranged adjacent a nose bone and a proximal end intended to be arranged adjacent a nostril. A screw winding is arranged centrally at the outer surface of the conical portion. A tab portion is arranged at the proximal end of the conical device. The nose device is inserted in the nose of the person until the distal end is positioned adjacent the nose bone of the person. Then, the nose device is rotated so that the distal end is positioned adjacent the nose bone of the person. When the nose device is rotated, the screw windings cooperate with the walls of the nose channel in order to pull them slightly outwards and stretch them, in order to thereby keep the nose channels open. A filter may be arranged for filtering the inhaled air.
