> Speaking of improvised masks, would vacuum cleaner bags be a good MacGuyver material that's present in almost any household? It's surely better at filtering than random t-shirt cloth, but would there be a risk of ruining lungs with fibers from the bag material? https://smartairfilters.com/en/blog/best-materials-make-diy-face-mask-virus/ https://smartairfilters.com/en/blog/best-materials-make-diy-... This notes it is very hard to breathe through the vacuum cleaner bag in comparison to a surgical mask. It is more effective at filtration. I’m not sure about the possibility of it releasing fibers. The analysis on that link suggests to me that for a DIY, cotton is probably the right balance although it doesn’t provide nearly the same level of protection as an official surgical mask.
