An improved, preferably plastic, universal breathing aid device for insertion into the nasal passages having a first pair of septum-engaging and gripping arms, from which are cantilevered a pair of curved, spring-action nostril-expanding arm that keep the nasal passages open. The septum-engaging arms are supported by a base member in the form of an open loop that includes a living hinge to provide flexibility and accommodation to varying sizes of nasal septums. The flexibility of both sets of arms promotes user comfort. The living hinge urges the septum arms together to provide grip yet comfort via the flexibility of the hinge. The nostril-expanding arms act in the opposite direction, opening the airway. The contours of the arm and tip cross sections may be varied for comfort, and device may range from generally planar to three-dimensional. The inventive device is unobtrusive and easily kept sanitary.
