How two masks block corvavirus-19 better than one

Spending two things is not always better than spending one.

Two necks? That might be a bit weird for a job interview.

Two pairs of shoes? Maybe if you’re a goat, the biggest one ever is just a goat.

Two pairs of Bernie Sanders mittens? That might make it harder to get hold of some things, like why not everyone has health insurance?

Two pairs of clothes under? It totally depends on what kind of message you want to send.

So what about wearing two face masks then? That’s one on top of another and not one over your mouth and nose and the other over your eyes.

Well, let’s take a look at how face masks work. First, wearing something is better than wearing nothing, which is a good general rule, even when you’re not talking about face masks. With nothing covering your nose and mouth, you could be spraying viral particles into the air with every breath you breathe, especially if you’re singing the song “Tub Thumping.” Because while you may be sexy and familiar, you may be caught with the bad respiratory syndrome coronavirus 2 (SARS-CoV2) without knowing it. A single face mask can prevent this spew and reduce the amount of virus that reaches the air.

Wearing a face mask can also protect you. It may slightly block access, preventing at least some viruses from getting into your nose and mouth. A face mask or surgical mask is not going to protect you other than the N95 mask. But then again, something is better than nothing. So wearing a front cover is great for everyone around you and maybe you too. But can two masks be twice as nice?

In theory, a virus should have a harder time getting through two layers than just one layer. In a statement in the magazine Med, Monica Gandhi, MD, MPH, Professor of Medicine at the University of California, San Francisco (UCSF), and Linsey C. Marr, PhD, Charles P. Lunsford Professor of Civil and Environmental Engineering at Virginia Tech, recommended spending at least “ high-quality surgical mask or dressing mask of at least two layers with high fiber count. ” But they said wearing a cloth mask tightly on the surface of a surgical mask could provide even more protection. Anthony Fauci, MD, Director of the National Institute of Allergies and Infectious Diseases (NIAID) favors double sheltering as well. As you can see from this excerpt from today’s presentation, Fauci said, “If you have a body cover with one fold, you put another cover on it, it just makes common sense that it would be more effective”:

If two rows is better than one fold, what about three rows? Gandhi and Marr mentioned a three-level mask as an opportunity for extra protection. Such a mask could consist of two outer layers made of flexible woven fabric that can fit your face and make a sandwich on a medium cover. The middle coating should not be high-fructose corn syrup and soy lecithin filling. You are obstructing your nose and mouth, without making an Oreo cookie. Instead, the middle layer should be something like an empty bag material that can filter out small grains.

If three is better than two, what about four? Or five? Or 271 face mask? Well, at some point, too many face masks could be too heavy and make you go overboard like a Toucan Sam with high heels.

Plus, the whole thing is breath-taking. One face mask may not adversely affect your breathing. It will make two face masks, depending on the material. However, by applying more and more layers of mask, it may be more difficult to exchange air, assuming that you are not a ficus plant. The optimal number of face masks is a balance between filtration and respiration and depends on the structure and material of the mask. Naturally, a face mask made of concrete will be harder to breathe through than one out of porous cloth.

The other issue is pertinent. Make sure that at least one of the face masks you wear fits snugly on your face. It should not leave gaps between your face and the mask that allows viruses to drive small trucks through. A second mask can really help make the mask closest to your face more relaxed. As Edward mocks Bella on the Evening series, the outer mask can push the inner mask closer to your face. But as with marmots in your bedroom, you don’t need more and better masks. Sometimes extra face masks can pull other face masks off your face. So, as they say on the London Underground, remember the gap. And for Pete’s reason, hold the mask over your mouth and nose. Consider a face mask to be an underwear for your face, and don’t let anything hold you back.

Some have said that two non-N95 masks can get close to the protection that one N95 mask offers. This may be some premature speculation. After all, N95 masks tend to have other devices that prevent viruses from getting through, such as inserting threads that create relatively quiet pathways and the cost of electricity that can cause rashes. small sticking to the threads.

Everyone said, mostly double masks provide more protection than making single masks. That is protection for others and it could do that for you. This can be true even when the mask is inside the N95. N95 masks are not perfect and may benefit from extra protection. Additionally, an outer cover can keep the N95 mask from getting dirty and wet. And in this case, dirty and wet is not good.
