HEPA filter vacuum bags make them "almost" as good as medical grade. There's a tutorial out there somewhere. The doctor gives the talk on the virus and then his wife does the mask tutorial using the bags.pinkbutterfly66 wrote: ↑Fri Apr 03, 2020 6:54 pmHuffpost has a link on the two mask styles. You need a liner that is water resistant. But something that is easy to breathe through. Dryer sheets I think was mentioned on one site and last night I tested swiffer dusting sheets and they definitely repel water and are breathable. But you need to test them with the cotton fabric as well. And ideally the filter part would be easily removable but still fit close to your face. I read last night, somewhere that they're now recommending the fabric type reusable grocery bags because they're breathable and water resistant. But the goal of the mask is protect others from you, not really protect you from the virus. So in that vein, two pieces of 100% quilter's cloth has tested as the best. Just make sure you preshrink it before you cut the mask out to make.Anonymous 1 wrote: ↑Fri Apr 03, 2020 6:12 pm Have any of you ladies made non-medical masks for yourselves? Since thats the recommendation now I guess I need to figure out how to make some. I've seen they should be 100% cotton on one website but I'm not sure why. Any suggestions?

Better than cotton which is used because of the fine weave. You use multiple layers so that the weave cross sects eachother limiting the holes that the virus can get through.
