2.3 Airborne SARS-CoV-2 Inactivation Experiments
In the first experiment, one of the electric heaters was located one
meter above the floor, as seen Fig 3(a). The other electric heater was
situated on the floor in the second experiment, as shown in Fig. 3(b).
The first electric heater has smaller power and airflow capacity than
the second one. Therefore, the first electric heater will be named as
“small electric heater” and the second one a “large electric heater”
from here on.
