Design of gas test. (1) Water control. The chlorine dioxide (ClO2) gas generator was filled with redistilled water (dW2). (2) Pre-treated control. ClO2 gas was generated for 9.5 min before spraying viruses, and the viruses were sprayed after switching off the generator and achieving the concentration that was low enough. (3) Virus was exposed to ClO2 gas produced from a generator containing 50 ppm ClO2 liquid for a few seconds.
