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. The nonconformities cause discontinuities between the exterior surface area and the nostril interior wall tissue, thus reducing the tendency to dry and stick. The nonconformities can be arranged in substantial alignment or randomly, can be uniform or varied in size, and can be resilient or inelastic. Each tube has a forward and rearward end that is inwardly tapered, thus eliminating the presentation of a right-angled forward or rearward end to the nostril interior wall tissues.
