Nice. And even more surprising so much discussions here in NL with our so called “experts” if masks would help..... amazing.

Is that a reasonable approximation to how much aerosol is expelled when a human exhales? b/c that video is quite different from this video from

The video I posted shows the leakage pathways, and it is a realistic simulation of those. But it is not a realistic simulation of human respiratory particles, which are shown better in other videos. Still, the points about fit can be made with the simpler simulation.

wow, super interesting how a cloth mask has visibility no leakage just because it has a better fit
i always feel skeptical about the fitted cloth mask because it has a cut in the middle but this video really helps me see it should be ok. thank you so much for sharing. -
Wow. How about it’s protection of the wearer?

@jljcolorado re: “stand behind” the plumes suggest a room w/ very low air velocity...what if the air flow were elevated back to front & wouldn’t in some case a Venturi effect be created at leakage points ie: flow across teller mask at open window at drive through at fast food -
I wondered that too. I think any mask will keep most of the leakage within the thermal plume and hence risk becomes the dispersed concentration when more than about 50cm. Interesting that mask fit affects leakage so much.
