Factors affecting aerosol SARS-CoV-2 transmission via HVAC systems; a modeling study
Fig 3
The fraction of individuals infected in simulated social gatherings increases with the assumed viral emission rate but can be mitigated by improvements to common HVAC systems.
Lines and points represent the median of 1,000 simulations, while shaded regions encompass the 25th to 75th percentile of results. *MERV 12, MERV 16, and any combination of UVC filtration of 90% and 99% efficiency with any mechanical (MERV-rated) filter produced very similar results.
