NOX Health Group, Inc.

NOX Health Group, Inc. (doing business as NOX Medical, a division of Arc Holding, Inc.) supplies polysomnography and portable sleep-monitoring devices with accessories and training to federal health and space research agencies as a prime contractor on sole-source purchase orders. The Alpharetta, Georgia-based for-profit company holds no set-aside designations and competes in the full-and-open market.

NOX Medical's federal footprint spans sleep-monitoring hardware and clinical evaluation devices. Recent work includes a $83,265.60 purchase order from NASA's Shared Services Center (awarded July 1, 2026) for five NOX A1 respiratory sleep-monitoring units with training to support the Fatigue Countermeasures Laboratory's crew sleep assessment during the MEA mission, with performance extending through July 2, 2029. The company also delivered a $58,387.26 order (June 8, 2026) for ten NOX T3S sleep-monitoring systems to NASA Ames and Johnson Space Centers for respiratory function and hypoxia-impact research. Earlier work includes a $20,475.00 polysomnography system with sensor kit and onsite training supplied to the National Institute of Mental Health in September 2022.

Customer concentration is split between NASA (two awards, $142 thousand combined potential value) and the National Institute of Mental Health (three awards, $58 thousand combined potential value), with one award from the Veterans Integrated Service Network 22 and one from the NIH Office of the Director. The company holds no parent vehicle seats; all awards are standalone purchase orders. Recent activity shows two awards in 2026 against one apiece in 2021, 2022, 2024, and 2025. A single sub-award under Research Triangle Institute (prime grantee, awarded December 31, 2025) rounds out the footprint. Combined potential value across all seven awards is $199 thousand, though combined obligated dollars total $938 thousand, indicating prior year execution against award ceilings that have since been completed.
