Patent ID: 6971388

Claim:
An internal nasal dilator filter for insertion in a user's nose comprising: two semi-cylinders of porous foam filter media each having a base with a flat surface and an end distal from the flat surface; a thin flexible band integrally molded with the semi-cylinders and extending between the bases; and a resilient member extending across the flexible band and onto a portion of each of the two semi-cylinders extending from the band; the resilient member flexibly urged into a substantially arcuate shape to place the semi-cylinders in parallel relation, the semi-cylinders sized such that upon insertion in a nostril the distal, end of each semi-cylinder is located inside the nasal vestibule and the base of each semi-cylinder is tucked in within the nostril just behind the ala, the resilient member urging the semi-cylinders against the nasal wall for outward biasing forces to each nostril so that breathing is facilitated.
