Discussion: Neither surgical nor cotton masks effectively filtered SARS–CoV-2 during coughs by infected patients.
The size of the SARS–CoV particle from the 2002–2004 outbreak was estimated as 0.08 to 0.14 μm (5); assuming that SARS-CoV-2 has a similar size, surgical masks are unlikely to effectively filter this virus.

- People complaining that the dish wasn't "far enough away" (don't care about this)
- Suggestion another tests should be done where the wearers are speaking normally (would like to see this)
- Complaints the averages may include records where not all data is available (that would be a problem yes)
- Different interpretations suggest the viral load escaping is reduced to 1/5th
