Abstract: A nasal air passage device is provided that includes connected tubes for insertion into the nostrils. The tubes support the nostrils' interior walls, allowing an increased amount of air to pass through the nostrils, particularly during sleep. Each tube has an exterior surface that has nonconformities, such as mound-shaped, including bubble-shaped, and ridge-shaped protrusions, and the like, that are distributed in a substantially uniform manner across the exterior surface.
