Has a new study claiming that neck stones like Buffs are worse than not wearing a mask at all. I’m not convinced this study should deal with the value of the face, but it ‘s also reasonable to suspect Buffs, bandanas, and other face masks that are not designed to do the job of a mask.
(To be completely clear: Buff is a company that makes thin, spandex-y neck jackets, which have become eponymously known to many as “buzzing”). they also make a face mask created for purposes. This mask was not tested in the study we are talking about here.)
For more face masks, watch the video below:
We have long known that N95 respirators do the best job of protecting the wearer and others. “Procedural” surgical masks – those medical masks available – are the next best thing, keeping most (but not all) of the breathing points to yourself, while possibly providing protection from others.
Since those masks are not always available, clothing masks are what most of us have ended up wearing. Clothes masks provide protection in a manner similar to disposable procedure masks, although they may not be as effective.
That said, not all masks are created equal. As we all tried to find masks for clothes, companies started advertising different types. Anyone selling guitar was advertising their guters; companies that made valve masks were selling valve masks. Of course, this does not mean that these are the best solutions.
Seed found this study
So far, there is no great way to test masks to see if they are “good enough” to protect against coronavirus. Medical masks pass some quality control checks, but fashion masks do not have such a protocol. Neither what you sew nor improvise at home.
So a group of researchers from North Carolina published a paper describing a free tool that can be used to test masks. The device is basically a box with a laser and a mobile camera; you stick your masked face up to the box and talk to it. The light from the laser emits droplets that splash out of your mouth (or do not hang, depending on how well the mask works), and is recorded by the camera.
The device does not test whether people are sick or given an infectious dose of the virus; simply looking for droplets in the air. No coronavirus was included in this test.
So to test the device, the researchers talked in boxes while wearing a variety of masks. As expected, people produced very few spots when wearing the N95, with surgical masks performing better and clothing masks varying depending on their materials and construction.
Here is the big remark: however: this was a test of the concept to see if the box could measure points, and if the points looked different from mask to mask. It not a final test of the masks themselves. In fact, the researchers write in their conclusion:
Again, we want to note that the mask tests performed here (one speaker for all masks and four speakers for selected masks) should only serve as a demonstration. Interdisciplinary changes should be expected, for example due to changes in physiology, mask adjustment, head position, speech pattern, etc.
What do we need to know about different types of masks?
First, if something is not really a mask, we should not expect it to perform as one. Both the CDC and WHO I recommend that a mask fits snugly around the mouth and nose, which excludes buffs as well as bandanas tied bank-thief style. They too warn not to wear a mask with an exhalation valve, as it just sprays your germy air into the world.
None of this is new. What is new in this study is the suggestion to be helpful can be worse than nothing because its weave open it seems to divide the largest points into smaller ones. that can qofsh problem See all those braided words? This is the best way to accurately describe the results. Buff it is very possible that buffs can turn out worse than nothing, but the question requires more study. No one has studied whether buffs actually increase the chances of someone getting sick.
I think it’s worth rethinking your buffalo, if you wear one. I know a lot of runners who want to have a neck circle so they can pull it off if they pass someone. We now have some clues to suggest that may not be a great idea, but we do already knew that an owl is not really a mask, so maybe we should not be relying on them in the first place.
