One embodiment of a nasal dilator comprises a pair of pads (100), supported by arms (110, 112) surrounding an air passage (115). Each arm has a bend portion (120) and a pad (121) that grips a wearers septum (615). Leg portions (125, 125′) extend down from the arms and are connected by a bight that surrounds the wearers columella (620). The dilator is installed by gripping an optional handle (130) or the bight and inserting the pads and the arms into both nostrils. The dilator is urged upward and inward until the inner side of the bight touches the wearers columella. To remove the dilator, the user grips the handle or bight and gently pulls downward until the dilator is removed. In an alternative embodiment, optional cushions (102, 122) soften the contact points between the dilator and the users nasal structures and can supply medications through the users nasal membranes.
