Patent

CA 2003895

A nasal filter positionable within a nostril having a nasal vestibule merging with a nasal passage of reduced cross-sectional dimension relative to the nasal vestibule. The filter comprises a body of resilient synthetic spongy material which yields upon radial compression to assume a compressed form of reduced, substantially uniform diameter permitting insertion into the nasal vestibule. The body further has a cross-sectional dimension when uncompressed such that when the filter has been inserted in the nostril and the spongy material has expanded radially, the body snugly fits within the nasal vestibule and causes an enlargement of the nasal passage.
