@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

@robinmonotti How big the particles are all depends on how you breathe, cough & talk & if youre sick etc: https://t.co/3PqBn1JfIz Virus particles comeback out as part of bigger ones. One stopped droplet = millions of microparticles. Cambridge masks
@aperfectstrange That said, aerosol generation seems to occur mostly in the lower respiratory tract, so it may not matter very much. https://t.co/1vmM1T8Yc1 It is not clear.

@B_relieF @JoeSilverman7 Here is a brief discussion: https://t.co/KXp74nzFV1
@JamesMelville The virus is carried in droplets. "The median mass is represented by particles in the size range of 0.7 to 1.0 μm" (https://t.co/gNNhPDsxry). It's gap between the fibres that is key. More layers means less of a direct path.
@Cass36786842 @curtisplayz1 @TeresaShank5 @JoeBiden All studies I've seen measure exhaled particles from the nose as negligible... The study linked mentions the nose, but only as part of the breathing process (in through nose out through mouth) https://t
@RowdyTrader @TIME Because you don't stop the coronavirus, but the water vapor you breathe out that carries the coronavirus. The fluid droplets mostly have the median size range of 0.7 to 1.0 micron. Smaller droplets may be exhaled too, but the masks are g
@NellyTells @GongSteve Epidemiologists unite. Stop wearing pants. Orifices should be free. The shit n bits particles you’ll share with the rest of your community is welcome. Just like what comes out of your mouth. https://t.co/ch9bqzjnzI
@yourlocalpogi @BeatByBenally Hi this is absolutely not a dumb question! Even exhaling through your nose produces droplets, which could infect others. New research suggests the virus may also be airborne, increasing risk of transfer https://t.co/sOkQljzj6T

#Covid_19 on what we exhale and how HEPA filters can help clean the air indoors The virus that causes COVID-19 is around 0.125 micron (125 nm (nanometers)) People exhale particles from 0.01 to 1000um ( 10 to 1,000,000 nanometers) https://t.co/xg4OxdnYpp
Nejpravděpodobnější za reálné situace (mimo laboratoř) je “létání” shluků částic (aerosol z dýchacích cest), které mají median velikosti 700-1000nm, které se rády dále shlukují a ulpívají na různých plochách a předmětech. (viz napr. https://t.co/GjXRCrGNkG
