The latter premise is false, as there is still some impedance to exhalation - air is not allowed through completely freely. That is not to say the impedance is great, but it must still be acknowledged that it exists and has an effect on the air breathed, however negligible. The matter, then, is one of 'to what degree', more than 'does or doesn't'.
- bena 5y agoIf there is impedance to carbon dioxide, then there must be impedance to COVID. That's what you and the other have missed. Or ignored. You can't argue that it both impedes carbon dioxide, but not COVID. And even if some gets through, it's got to be better than all. I thought we weren't supposed to let perfect be the enemy of good.
- ghoward 5y agoJust because COVID is impeded does not mean the mask is effective. The mask might impede COVID by 1% and carbon dioxide by 0.5%. That means the mask is 99% not effective against COVID, but a model I created [1] shows that even the 0.5% impedance will eventually lead to the mask keeping in half oxygen and half carbon dioxide, leading to higher carbon dioxide inhalation.

Mayo Clinic disagrees with your program. So of the two options: the Mayo Clinic being wrong, or your assumptions being wrong. I'm going to go with your assumptions being the one that's wrong.

- bena 5y agoHow does that refute the fact that the Mayo Clinic says that wearing a mask won't give you hypoxia? Also, what's the date on that article? Because it looks like April 2020. There's been several studies since then, along with just the raw statistical data, that shows masks do help. https://www.npr.org/sections/back-to-school-live-updates/2021/09/10/1035954587/yes-gov-desantis-studies-do-show-masks-curb-covid-19-in-schools https://www.npr.org/sections/back-to-school-live-updates/202...
