Abstract: Apparatus for controlling air flow through nasal passages having a frame with first and second plates for positioning on a face along opposite sides of a nose. The plates have first and second extensions extending forwardly and inwardly and contacting a face of the user beneath the nose and above an upper lip. Rods extend inward from the plates, and nose-engaging pads are mounted on inward proximal ends of the rods. A strap connects the plates and extends rearwardly around a head of a user. The strap has first and second sections with hook and loop complementary fasteners for adjusting the strap to fit a head of a user, and holding the strap. The extensions have a curved bar which slides within a curved channel for adjusting the position between the plates. A threaded clamp has an enlarged head mounted in an elongated recess at the rear of the channel, and has a shaft which extends through an elongated opening in the channel and through an opening in the extension which slides within the channel.
