GRB Technologies

GRB Technologies, now also operating under the Sphaira name, is a Quebec-based healthcare technology company developing infection-control devices for hospitals and other indoor environments. Its products are designed to reduce transmission of pathogens through contaminated surfaces and indoor air, with flagship technologies including LIBU, an antimicrobial elevator button, and LIFA, a UVC-based air sanitization device. The company appears to focus on non-drug prevention technologies rather than therapeutics, positioning itself at the intersection of medical devices, environmental hygiene, and public-health infrastructure. GRB/Sphaira has collaborated with Quebec research and innovation institutions and promotes its solutions primarily for healthcare settings and other high-risk enclosed spaces. Available evidence suggests it is a small, private, active Canadian company with early commercial activity and ongoing product development.
