A new market forecast from Nexalu Group projects the global ultraviolet-C (UV-C) disinfection systems market will reach US$8.12 billion by 2033, driven by heightened infection prevention and control (IPC) requirements and rapid advances in AI-enabled and smart disinfection technologies. However, research published by Cambridge University Press reveals a disconnect between the growing adoption of UV-C solutions and how cleaning teams perceive and understand their use. While UV-C technology offers clear advantages—including reduced chemical reliance, operational cost savings, and improved staff safety—its successful deployment ultimately depends on robust training and education programmes. 

This shift is reflected in recent updates to the U.S. Green Building Council’s LEED v5 standard, which now recognizes the use of UV-C disinfection devices. Operating at approximately 254 nanometers, UV-C light penetrates microbial cell walls, inactivating bacteria, viruses, and fungi, according to LightTech LightSources. Experts note that, when correctly applied, UV-C can significantly reduce healthcare-associated infections (HAIs) without leaving chemical residues. Nevertheless, its effectiveness remains closely tied to correct usage by frontline cleaning personnel. 

The Massachusetts Institute of Technology (MIT) emphasizes that UV-C deployment must be supported by clear operational guidelines and targeted training, including visible warning signage, defined disinfection protocols and schedules, and registration of UV-C devices under the U.S. Environmental Protection Agency’s Radiation Protection Program (RPP). Despite technological advances, the International Agency for Research on Cancer (IARC) continues to classify UV radiation as a Group 1 known human carcinogen. As such, UV Resources advises commercial cleaning leaders to minimize worker exposure and ensure the consistent use of appropriate personal protective equipment (PPE), including UV-blocking eyewear, gloves, and long-sleeved protective clothing.
