Fig. 1. Schematic representation (left) and real photography (right) of the hospital two-bed room at which the experiment was conducted. Eight humidifiers, two thermo-hygrometers, and one circulator were used for the experiment. The bactericidal effect of atomized HOCl against two bacteria, carbapenemresistant Acinetobacter baumannii (CRAB) and multidrug resistant Pseudomonas aeruginosa (MRPA), was evaluated. HOCl, hypochlorous acid water.
