SARS-CoV-2 is an RNA virus that has a diameter of approximately 0.1 μm. It is transmitted by respiratory droplets and aerosols such that one of the most effective ways to prevent infection is to wear filtering facepiece respirators (FFRs). The commonly used FFRs are N95 respirators, devices that by design filter 95% or more of particles larger than 0.3 μm in diameter. In practice, these devices prevent the passage of 99.8% of particles larger than 0.1 μm.1 RNA viruses are inherently unstable, and transmission of viable SARS-CoV-2 can occur only if the virus is protected from the atmosphere by being contained within moist respiratory droplets or aerosols.
