Nasal Valve Support is a nasal breathing product offered by Allied Advanced Technologies Corporation, based in San Jose, California. In commercial use since 1989, its Nasal Valve Support is an internally worn, reusable insert designed to help keep the nasal airway open. Each support is custom designed and manufactured for the user’s problematic nostril, fitting between the nostril’s side wall and the septum. The company describes it as discreet and comfortable for use during the day, at night, or both, without medication or surgery.

The product is intended for people seeking support for obstructed nasal breathing, including issues associated with nasal valve collapse, narrow nostrils, or a deviated septum. The website also discusses related concerns such as snoring, mouth breathing, and sleep difficulties, while individual results may vary. Customers can find information about sizing, safety, effectiveness, pricing, insurance coverage, and whether the support may be suitable for them. The company offers ordering through its website and promotes a 100% money-back guarantee.
