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

Figure 8

Model predictions of the concentration of infective virus (log₁₀ scale) in rooms of varying size, as a function of time. Each room was assumed to be operated under conditions of 1.0 ACH and a well-mixed air space. A single emitter (π = 10⁵ viruses/hr) was assumed to be present in the room for the period ; air treatment was assumed to be initiated at at a constant condition of and (). Vertical dashed lines indicate initiation of treatment (blue) and departure of the emitter from the room (red).
