Such a scam.
How Effective Are Cloth Face Masks?RANDOMIZED CONTROLLED MASK TRIALS AND OTHER DISEASES
At least 14 RCTs have assessed the relationship between mask-wearing and non-SARS-CoV-2 respiratory infections, 13 of which failed to find a statistically significant benefit in the main treatment group. For example, a 2012 cluster-randomized study at the University of Michigan found 46 (11.7%) of 392 students in the mask group tested positive for influenza-like illness compared to 51 (13.8%) of 370 in the unmasked control group, a difference that was not statistically significant.
Actually,I question how well they work to filtering most out dust particles.
If they reduce dust then why do I have a big dark spot..NOT on the outside of my mask..but on the inside of my mask?
I agree with you about masks stopping particles from coughing or sneezing - but who does that? I’ve watched as the Resident took off his mask, coughed, and put it back on. And really, who wants to keep wearing a sneezed-in mask?
:)
Yeah..most people do not understand basics of contagious diseases and how vaccines work.
For example many people think a vaccine is supposed to stop infection from the specific virus. This is physically impossible since no vaccine has ever been successful in constructing a filter in nose to stop virus particles from being inhaled. Only thing vaccines do is try to stock up the body with additional anti-bodies for the specific virus. Therefore vaccine’s role begins AFTER one is infected, to help kill the virus before it makes you seriously sick.
This role of vaccine has worked so well, that people think the vaccine stopped the virus from making you sick. Not so. You had to get infected first. But because most vaccinated people never get symptomatic sickness, it appears like the vaccine “prevented” infection.
Oh, sheet.
If I hear that whiny, nasally self satisfied arrogant Whitmer’s voice again saying “I follow the science” and “We’ve saved thousands of lives” I’m going to scream.
Minor correction. It is physically impossible for the kinds of masks people are using to protect you from inhaling airborne viruses. There are masks that do reduce your risk of inhaling airborne viruses. N95 masks with careful sealing and use are helpful. The CDC knows this, that's why they publish articles telling people to use that kind of mask when there is a chance of exposure to a dangerous virus.
In situations where a known dangerous virus is present you will see much more sophisticated respirators in use. Nobody uses a cloth mask in a P3 or P4 lab.
From the CDC:

N95 frequently changes
D? A little bit. Cloth masks don’t do crap to keep the germs from a sneeze or cough out. Cloth masks are not even good for wiping one’s bottom.

You need to sign up for Physics-101. Then we can discuss intelligently. I have masters degree in mechanical engineering.
Congrats but cheap cloth masks (frequently stuffed in a pocket and worn multiple times) worn by the sheeple are worthless and for virtue signaling only. Even a simpleton history major like me knows that.
Do this simple experiment. Turn on your sink faucet half way. Observe rate of water flow. Then cover the faucet with a simple cloth mask. The flow will diminish significantly. What that means is an infected person coughing with mask on will exude LESS virus material in air. Which is always better than full expelling of virus material in air.
