@Graham_Wharton @rubrogram "Large respiratory droplets" - nice try - but no. "All": Exhaled particles range in diameter from 0.01 and 1000 μm" "The median mass is represented by particles in the size range of 0.7 to 1.0 μm." https://t.co/dKdQQgwVz4 Vap

@Doceos1 @michael_hoerger @WHO 90% of human exhaled breath particles are under 6 microns. The average pore size of a n95 mask is 30 microns on the lower end. Active COVID particles are 1-4 microns https://t.co/Ls5SzG6uMW

@CardsInTheAir @Nagu_360 @KimSmit56027309 @ringothe5th @amberloyse Here is an interesting read ... in some parts you can understand the limits of how we can measure molecules < 1 ųm and smaller. https://t.co/XXVSnoGYpt

@Sophie67628893 @TheMapRoom @BernieSpofforth Exhaled droplets also pass through the weave of cloth masks.. they are small particles also…and pass around the masks. Paper masks people wear do nothing. All show. https://t.co/3nZcMKlQH4
