Abstract
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 an elongated cylindrical body of resilient synthetic spongy material which yields upon radial compression to assume a compressed cylindrical form of reduced, substantially uniform diameter permitting insertion into the nasal passage. The body has a length sufficient to extend through the nasal vestibule and into at least a portion of the nasal passage. 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.
