They dont protect others or you.The cloth masks we are wearing are to protect others, not ourselves if we should have COVID and not know it yet. You can take it off any way you want. Anyway, if others don’t know how to take a mask off without contaminating themselves, that’s THEIR problem.
Yep. An N95 does provide decent protection. Without the exhalation valve or even with one they are pretty darn uncomfortable. Especially for someone who's lungs are already compromised by COPD etc..An N95, fitted and worn correctly, is pretty darned good at keeping germs of any sort at bay.
Yep. That's the official propaganda.The mask is there to stop contaminated aerosol particles from hanging in the air for several minutes after a person coughs or sneezes.
Since the viruses are usually contained in the aerosols, the mask is somewhat effective.
certainly not as effective as a positive pressure breathing apparatus, but better than nothing.
GOV.UK. Evidence suggests that wearing a face covering does not protect you. However, if you are infected but have not yet developed symptoms, it may provide some protection for others you come into close contact with. It is important to use face coverings properly and wash your hands before putting them on and taking them off.
A close relative asked me about the idea of masks and whether a roughly-woven, homemade cloth covering could do much, I asked this person to review the size of viruses and other "bugs" (in microns) as compared to the size of particles guaranteed by such materials to get filtered out (at least, at a given level of 'efficiency').All that is simply control and making people think they are doing something.
Bottom line is if your not wearing at min a n95 mask, and your susceptible to the virus if you are in its presence you will likely catch it.
The exhaled virus material is necessarily carried by liquid droplets which do get trapped in the mask.A close relative asked me about the idea of masks and whether a roughly-woven, homemade cloth covering could do much, I asked this person to review the size of viruses and other "bugs" (in microns) as compared to the size of particles guaranteed by such materials to get filtered out (at least, at a given level of 'efficiency').
All of which presupposes any face covering is tightly-sealing, of course; which most of them aren't.
The SARS-CoV-1 virus is about ~0.125 microns, whereas the NIOSH N95 graded filtering is measured for 0.3 micron particulates at 95% effectiveness. Even the N100 grading is for 0.3 microns, but at 99.97% 'efficiency'. Which means that the SARS-CoV-1 virus is likely to get through if it's in much concentration in the nearby air. In either direction. Even on a N100 mask. Particularly if not tightly-sealed to the face around the mask.
There are some mask companies claiming meeting of the NIOSH N95 standard that say they filter out far smaller particulates (down to 0.075 microns, such as Allegiant Med Supply).
But, with the NIOSH N95 standard for such common facemasks being at 0.3 microns, and the size of this virus being about one-third smaller ...
How dull life would be without these little bumps and turns in the road.
I'm assuming you are in agreement with Governors issuing executive orders that effect private citizens and businesses, even though their state laws prevent them doing so? As evidenced by Beshear being struck down the same day.I really get a good laugh at all of the "deep state" conspiracy paranoia on this subject.
Seems the beer hall lawyers are now beer hall doctors as well.
Alex must be proud.
