That seems to support parent's comment.

Yes, some smoke does leak, but compare that to him exhaling without a mask. You would g…

I wonder how no one came out with a better version with some filter "installed"? Is this the best we can do?

You mean a mask which filters both on inhale and exhale? N95 masks do a decent job of that, although I'd guess there's still some leakage on exhale (not designed for that). N95s are still sold out in my area, so I got some KN95 which I use. The CDC tested some of them for effectiveness, many of them got pretty high marks: https://www.cdc.gov/niosh/npptl/respirators/testing/NonNIOSH...

"Disposable" medical masks cost pennies to make, can be worn for multiple days, and are highly effective. In an environment where some folks refuse or can't mask, they are the most effective way for people to keep themselves safe.

By the way, I don't make or sell masks. I'm just interested in keeping people out of the hospital and my friends/family safe.

Some of the KN95s have been found to be counterfeit. Some of the ones we tested were no better than a cloth mask. When buying KN95s, please check that they've been validated by the CDC's list.

If it's legitimate KN95, it probably protects at least as good as a medical mask but probably not as good as a N95. This is because KN95s are not designed to form a complete seal so many folks will have some leakage around the edges. This is the reason that you see many systems 3d printing molded frames to improve the KN95 fit and decrease leakage.

You don't know if you have flu or not either and yet no one has worn masks when there is a flu season.

are you comparing the flu to c-19?

Mortiality rate is close:

Fauci: “The seasonal flu that we deal with every year has a mortality of 0.1%.”

Mortality for Covid is 0,14%: https://www.dw.com/en/coronavirus-who-estimates-10-of-global...

Dr. Anthony Fauci talks with Dr. Jon LaPook about Covid-19 – Masks are only important for infected people to protect others. There is no reason to wear masks and it might even make people MORE sick: https://www.bitchute.com/video/G4EqLeo3xoU3/

Fauci said himself he lied lol.

This word lied. I do not think it means quite what you think it means.

Proving exactly how effective masks are, and why, is a luxury we don't have right now. We can't ethically do the experiments that would give conclusive results. Arguing about the details takes up energy that could be used to keep us safe in other ways. Wear them just in case. Do not let them be your only defense. Cover your eyes. Don't talk to people up close when you're wearing a mask if you can help it. Breathe through your nose. Don't shout at each other about god knows what like the dumb ladies in the laundromat standing on either side of me the other day, putting me in their microbial crossfire.

This video only claims that YOUR mask doesn't protect others from your breath. This seems like a good reason for BOTH parties to wear a mask.

To be clear: you're saying that we don't see any benefit with rigorous science. We only see the benefit when we drop our standards of evidence.

How are sociological studies any less scientifical? Is the human behavior something not worth studying?

Because it's not science. Spain has been wearing masks for months now, 99% of people comply and it gets only worse and worse. Both of our statements are anecdotes.
