Using vapes to prove masks don’t work is dumb

ok this bothered me enough to look it up and my hunch was right.

I saw a video from a doctor proving masks don’t work. This is a typical example screenshot: he sucks in a giant hit on a vape pen and then exhales a cloud of vapor around the edges of a very (intentionally) ill-fitting mask:

ok so how big are the particles exhaled by people who vape?

Call it 1 micrometer. Well fine, viruses are smaller than that, right? Right, guise?

There’s a difference between the size of a virion and a particle someone exhales than can carry it into your mucosa. The filtration of a mask obviously depends on the kind and fit of the mask used, but come on here. If you’re doing science, don’t be obviously wrong and/or disingenuous.

If you’re demonstrating a filter doesn’t catch particles, stop using something 5 to 30 times smaller than the thing you’re demonstrating it doesn’t catch. All of which is beside the point. The video from the first picture here, shows that most peoples’ masks DO work . . . to keep from spreading high-velocity large particles. See how he was blowing clouds of small bits out the sides?

Masks catch the big chunky aerosols. That’s the deal. That’s what they’re for. A surgical mask prevents your cough and sneeze juice, as well as your mouth-breather breath, from blasting out straight at the person in front of you. They leave a cloud of smaller particles that evaporate and are not hazardous, or agglomerate and fall down within ~1meter of yourself.

Saying “masks don’t work” because they don’t provide 100% protection is silly. Nothing but sealed Level IV Virus Protection Super Suits with forced air from a HEPA filter is gonna be 100% proof.

yeah, but…

Oh, and since that’s the next question. Yes, masks filter out fine particles. Even this article saying they aren’t perfect shows that they do work to some degree. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7115281/

Mask *mandates* don’t work because people can be responsible adults without being told. Maks *do* work, but only for what they work for. This is not an open question.
