Validation of In-Room UV-C-Based Air Cleaners

Figure 3

Summary of airborne, infective T1 phage concentration vs. time for five operating conditions of the air cleaner. For each experiment, represents the time at which introduction of aerosolized T1 was initiated; represents the time at which the air cleaner was turned on (i.e., when air treatment was initiated), with operating conditions as indicated in the legend. Four of the five experiments were conducted at the air flow rate () that represented the design condition, 1020 m³/hr; one of the experiments was conducted at a higher air flow rate () of 1530 m³/hr.
