HealKEE Medical is a Singapore-based medtech company developing AirKEE modular healthcare environment systems and AeroKEE procedural source-control solutions for healthcare infrastructure, infection control, and occupational safety. Control is not given. It is engineered — and rooted in care. ABOUT HEALKEE HealKEE develops clinical solutions at the intersection of healthcare infrastructure, infection control, and occupational safety — establishing two new categories that extend control from the environment to procedural exposure. AIRKEE® AirKEE enables complete coverage across critical healthcare environments, including operating theatres (OT), airborne infection isolation (AII), and protective environments (PE), through mobile modular deployment that reduces reliance on traditional fixed infrastructure. AEROKEE™ AeroKEE is designed for procedural source control during aerosol-generating procedures (AGPs), extending protection across gastrointestinal endoscopy, bronchoscopy, and ENT procedures through single-use, patient-worn solutions. HEADQUARTERS Singapore Operating from a global MedTech hub with strong regulatory integration and access to international clinical markets across NA, Europe, and Asia-Pacific. ISO 13485 CERTIFICATION Certified medical device quality management system aligned with global regulatory standards, enabling consistent deployment across international healthcare environments.
