The advantages of UVC based systems are not only limited to the greater effectiveness of the method, but also extends to the time factor which is often critical decision making factor with regards to disinfection of rooms between two procedures. Chemical-based cleaning like Fogging or Fumigation is often found to be unsuitable for situations which need quick yet effective disinfection.

The UVC-light based disinfection system must operate in unoccupied rooms, example: after the patient discharge and in the absence of health personnel. Many devices have motion sensors that shut-down or pause the device if any movement is detected inside the room being disinfected. Implementation of this “no-touch” technology in various hospitals has documented a sustained reduction in surface microbial contamination, reduced cross contamination, and a reduced spread of multi-drug resistant bacterial infections.
