Does tyvek stop covid?
    #26576935 - 04/04/20 09:24 AM (3 years, 9 months ago)

I'm seeing people making cloth masks which are pretty much useless. Like shooting bb's through a tennis racket. Will tyvek masks stop it?

cloth masks are better then nothing I think, maybe im wrong, but I think a cloth mask is usefull for limiting the spread if you have the virus and cough, although it will do nothing from stopping you from getting the virus

since masks were like $50 on Amazon, I just wear a neck gaiter, plus I seen someone here say it looks cool when everyone is wearing bandanas and shit, I agree

Interestingly:

Quote:

As NPR has previously reported, some research has shown that cotton T-shirt material and tea towels might help block respiratory droplets emitting from sick people — though it's not clear how much protection they provide.

Another study, of health care workers in Vietnam, found that use of cloth masks resulted in greater infection than either those wearing surgical masks or a control group, some of whom also wore surgical masks.




I wonder if it's because people have a tendency to wear cloth masks directly against their nose and mouth whereas respirators and surgical masks hang away from the face some. This was among medical professionals so they're less likely to be making the common mistake of touching the mask, pulling it below their nose, or improperly reusing it.



Also feel right bad for Vietnam. They were supposed to host some big Indie cup this year, the first time they had ever hosted such a big western based event. Maybe the first big even they had ever hosted. That's of course cancelled now.

Probably depends how often you are changing the mask as well. Ideally you are swapping an N95 regularly. Cloth masks maybe not as often.

That could be. I imagine you would want to change a cotton mask more frequently than you change a respirator.

Might work.

Crazy_Horse had a great idea of modifying HEPA Vacuum bags into masks. I have a square HEPA filter made for HVAC systems that i am probably going to cannablize into some masks.

The cotton/cloth masks are entirely to catch respiratory aerosols from projecting out.  My guess the mixed study from Vietnam, was due to wearing sloth masks too close/tight and breathing out through them leading to spraying accumulated respiratory fluids outwards.  If you have ever warn your common hospital mask, you will notice your breath hits the mask but exits the sides/top(foggy glasses).  This is entirely to absorb respiratory droplets, but not push them though the mask.

As long as your mask has a N95 respirator in it, it will protect you. If you are using a surgical mask it is just going to protect other people from you.

And it is properly fitted, and you don't have a beard (slightly redundant) and the cartridge is not expired.

You'll touch your face less and it'll still catch particulats.
It isn't aerosolized, so if it's catching your spit, its protecting othern people

Muat have people living under rocks around here.

Haven't you heard, mask don't do anything and you're wasting your time covering your face holes.

You would need to triple layer it. 20 microns is the size that would work. Tyveks are usually plastic bag things. It isn't really fool proof but helps.

IMO, tyvek would be a little difficult to breath through, as the stuff I get from the post office is pretty tightly woven, more like paper, like an envelope ya know?

Try Cheese cloth layer 3 together make sure to glue around the seams. Then add a rubber band or string.

Diagram. You can cut the cheese cloth into a mask but as long is it covers nose and mouth it is good.

Cloth surgical masks are way better than nothing. Filters out like 96% of particles


Pillowcases work ok too

Obviously an n95 is better but plenty of medical personnel were walking around without n95s during the first few weeks of this. Obviously a few got sick but most did not

N95 masks are disposable after 8 hours for that very reason. They aren't washable either.

This is why half mask and full face respirators use the thermoplastic elastomers for their construction, they are easy to clean. The filters actually increase in effectiveness as they get used as the filters them selves clog and filter ever more tiny particles. The problem is that this induces respiratory stress of its own. So to wear this type of protection you have to pass a medical evaluation in industry. Citizens are free to wear what they like, but be aware that increased respiratory stress isn't something you want to experience if you aren't reasonably fit. People with heart or lung conditions should avoid respirators.

As for these ad hoc methods, they likely help muffle emissions, but they are no where near as effective as proper PPE. I would think something like a thicker felt would be quite effective, but it may be too limiting. Suffice it to say, tight knit fabrics that aren't suffocating will be the best.
