Some masks better than others

Sometimes it's just 1. The middle one... because it's the one that works best.
The fact you say it's not right actually mean's it is because you are wrong about everything.
does masks help - Google Zoeken
www.google.com
Honestly beyond pure idiocy....
I can show you google links for ANYTHING
The fact you find some conspiracy nutjobs who think masks work and believe them says alot about you
Conspiracy nutjobs eh...
The links are for the Mayo Clinic, University of California, Healthline, the CDC, University of Maryland....you're right, they are all well known conspiracy nutjobs.
Your link is clearly a random google search
Want to quote Mayo etc?
Then link them
The google search has those links.
I'm putting you on ignore...you are an annoying human.
HAHAHAHAHAHAHA, holy shit. I was sipping on a redbull and I spit it out laughing. Teejay calling other Conspiracy NUTJOBS and not too mention covididiots when all he needs to do is look in the mirror! AHAHAHAHAHAHAHA,
You've provided no evidence - nada, zilch, nil - that mask wearing "hasnt done a damn thing".
How is it, then, that after masks were widely used in the Czech Republic infections dropped?
How is it, then, that studies say that after mask mandates in the USA & Canada infection numbers fell?
How is it, then, that mask wearing Asia did so much better than maskless Europe?
Scientific evidence support the effectiveness of masks:
" The science supports that face coverings are saving lives during the coronavirus pandemic":
Face masks: what the data say
The science supports that face coverings are saving lives during the coronavirus pandemic, and yet the debate trundles on. How much evidence is enough?

Coronavirus Disease 2019 (COVID-19)
CDC provides credible COVID-19 health information to the U.S.
Still Confused About Masks? Here’s the Science Behind How Face Masks Prevent Coronavirus
We talked to UCSF epidemiologist George Rutherford, MD, and infectious disease specialist Peter Chin-Hong, MD, about the CDC’s reversal on mask-wearing, the current science on how masks work, and what to consider when choosing a mask.
If, as you say, there is no way to say for sure whether masks work or not, why should we admit "masks don't work"?
Which is it? They don't work or there's no way to know if they work. Make up your mind!
There's tons of evidence in support of masks being effective at saving lives. And it's been posted in the mask threads here. It's also just common sense.
No such comment from the CDC exists. In fact the CDC recommend mask usage.
Wrong. See the threads i posted urls to above.
Just have a few dozen KN95 masks & alternate them. By the time you get back to the first mask in 3 weeks any virus on it will have died.
Ditto for surgical type masks that are similar in their protective effectiveness.
That's like the dumbness of saying a rise in any one place at any time in deaths from bicycle or motor cycle accidents proves that brakes & helmets don't work.
That's like the stupidity of saying a rise in any one place at any time in STIs from sexual activities proves that safe sex and condoms don't work.
That's like the ignorance & faulty logic of saying a rise in any one place at any time in deaths from motor vehicle accidents proves that seat belts & airbags don't work.
The fact is without those safety measures, just like without masks, the number of deaths would be even worse, even higher.
I know why I pointed my finger at you. And for what reason(s) are those 3 pointed back at me.
He's promised that he has studies and will publish them, but when the time comes to shut us up he becomes too lazy.
Okay you wanna see studies, here's a whole bunch of them.
First read this. Its basic science. And EXACTLY what I've been saying all along:
Before the COVID-19 pandemic, I was part of a research team investigating the design of health equipment, including masks. Masks are important for protecting healthcare workers. The Centers for Disease Control and Prevention may even suggest that the general population start wearing them in public (contradicting previous advice). But masks aren’t foolproof. That’s because many of them are poorly designed.
A basic understanding of how masks work helps. Masks are filters. The material used in a standard surgical mask (by far the more common type of mask) reduces transmission of bacteria. Both bacteria and viruses are microscopic microbes, but they differ greatly. Bacteria are living cells, while a virus is a particle that requires a host cell to replicate. A coronavirus virion (particle) is spherical, averaging around 125 nanometers in diameter. Compare that to bacteria’s 1,000-nm size. It’s a grape compared to a grapefruit. A surgical mask whose purpose is to block bacteria will do little to prevent passage of the smaller coronavirus particle. That’s why N95 masks, which block 95% of all airborne particles, are the gold standard in hospitals treating COVID-19 patients. They have a much more selective filter.
But even N95 masks are flawed. Before coronavirus, my team and I investigated whether N95 masks could be a viable alternative to standard surgical masks. Interviews with doctors and nurses at several hospitals at the time revealed that N95 masks were rarely used or supplied. The overwhelming majority of healthcare workers I spoke with had never worn one. They are more expensive than surgical masks, they’re harder to breathe in, and medical workers deemed them unnecessary for most procedures. (Keep in mind that masks protect in both directions. They protect the wearer from airborne particles or splash, and protect the patient from contamination by the surgical staff—the latter is especially important in procedures that require deep incisions.)
Problematically, masks seem like they weren’t designed for people’s actual faces. Although some masks require two ties around the back of the head, doctors we observed often just tied one—it’s easier to breathe when one is left loose. (The nurses were generally better behaved.) What’s more, tying the straps around your head might cause the mask to pucker at the cheeks, creating gaps; and gaps above the cheekbones result in an upward flow of breath that fogs glasses. Even just talking can make the mask creep down from the nose. Yawning does the same but more quickly. Biomechanically, face movement and mask movement don’t align—the jaw’s pivot point is near the ear, while the mask flexes near the mouth.
Compare an eighth-inch gap at the cheek with a bacteria cell or virus particle that can only be detected using an electron microscope, and you can understand why many are skeptical that masks can protect the masses, let alone healthcare workers.

(2009) “Use of surgical face masks to reduce the incidence of the common cold among health care workers in Japan: A randomized controlled trial,” American Journal of Infection Control, Volume 37, Issue 5, 417 – 419. N95-masked health-care workers (HCW) were significantly more likely to experience headaches. Face mask use in HCW was not demonstrated to provide benefit in terms of cold symptoms or getting colds:

Face mask use in health care workers has not been demonstrated to provide benefit in terms of cold symptoms or getting colds. A larger study is needed to definitively establish noninferiority of no mask use.
