Mask questions here.
Okay, so it seems clear that cloth masks are not that effective. N95 for medical use are unavailable. N95 for general use are available many places (but banned in some places because particles can escape them, so some places banned them on public transport).
However, most of what I'm reading does not give cloth masks a good protection score - at all. N95's don't block everything incoming, but between 40-60%. Cloth masks, depending on the cloth, block 3-20% of aerosolized particles. The study I read was done regarding nurses and their masks, in places where nurses had to make their own cloth masks.

Those of you who learned to pleat and double/triple fabric were on the right path. Now, it looks like some kind of neoprene-like fabric is being used.
Here's the thing - I intend to social distance. I do not want people closer than 6 feet and I'm only going to be outdoors when there's a breeze. So...a plain cloth mask (I have one, have to toss it) only blocks 3% of aerosolizd particles. Pillow case fabric, doubled, may block 40% (but again - I don't intend to be near anyone in the first place).
So - what are your mask ideas? I'm more concerned about incoming virion than outgoing, as I know I do not currently have CoVid, but I would like to do something other than pace around the perimeter of my own yard one day.
They sure have. Here in California, protein has gone up in cost, no matter what type it is. I look for it to get worse before it gets better, as California is facing a difficult decision about whether to keep its borders open to cheaper eggs, meat and produce from elsewhere - if there's a risk to it. The news about the two main strains of CoVid is very sobering. Will we give up and just eventually let it come to our state?
Stay tuned. Gov Newsom - if you're reading, what are you going to do there?
I would try to get a homemade one with a filter pocket. I'm leery of the blue shop disposable towel because I think it would draw moisture from your breath. I tend to gasp for air while moving freight, though. It might be different if you can breathe through your nose. Jmo
