Default Duke ranking of 14 MAsks

https://www.aarp.org/health/conditio...ks-ranked.html

at last a ranking of which masks work the best.
Ideal would have been to do this study sooner, but it may be complicated. Seems cdc could have pushed this eary on, but it is good to have it.

Neck gaiters and bandanas are worse than no mask at all.

It would have been nice to put the photos in numerical order! That kicked my OCD into overdrive.

not really. The point is not to stop single viruses floating in the air. The point is to stop the droplets that you spew as you breathe and talk. Those droplets can be trapped by most mask materials.

They missed testing the efficacy of one mask...

I guess the AARP group ruled out recycled "wife's undies" for masks!

Didn't even make the list.

If masks held water then you would carry water in a mask, not a bucket.

You know what IS nasty everywhere? Floors. I've gotta disinfect/burn my car after travelling thru 6 states in 5 days. Floormats are clean but "filthy".

Do you realize how small a virus is? Obviously not.

Almost interesting. Most "studies" have a discussion of methodology and metrics. This appears to be anecdotal and not scientific.

I'm not pro-mask, but the idea, and actual principle is that they kill the momentum of your spit particles. Sure they may ultimatly get through, but they aren't going to make it far, and are less likely to get fully mixed with the air like in a sneeze of cough.

I think if people went back to basic hygiene, coughed into their elbows or handkerchief like the old days, and held their sneezes to themselves, we wouldn't have masks being forced on us. Oh and washed their damn hands!

horse poop. Masks would be required either way as many people have high anxiety and fear that drives theirs lives. But you are correct on the whole...

My mask fogs my eye glasses. Fog is droplets. Hint-aerosol
Viruses live in all sized droplets.

The study "measured" droplet transmission. Bogus "study" because there was no standardization of droplet sizes from humans, because droplets come in all sizes.
Media says it's "scientific." Duke University! In this case, it's causal association. The study is pretty much of no value other than click bait. It will reinforce biases.

Takeaway. Some "masks" stop some droplets. No known scientific effect on COVID outbreak.

NPPTL ( National Personal Protective Technology Lab) the agency that tests for NIOSH did a test a while ago. They had similar results but with n95 masks. The difference is NPPTL actually says while the mask itself may be effective, the mask needs to be worn properly and fitted correctly, and makes no claims one way or the other and will not certify the tested masks. This test and the one that NPPTL did only tests a given mask. Not an individual wearing it on a regular basis. There's simply way too many factors for any agency to stick there neck out officially.
