Cloth masks have been proposed as way to address shortages during a pandemic. Here are 3 articles from PubMed on the subject.
Short story is… you really don’t want to be in a situation where you have to resort to making one. Cloth is basically worthless at filtering viruses.

All
What do you say to a healthcare provider (assume they are in your core family) who has been told to ration N95 masks. Told to reuse them.
Healthcare provider wants to know about sanitizing them; about effectiveness; about building their own mask.
FYI, here is some NIH published data:
Reduction to exposure by virus-like particulates. Based on article published by NIH
Mask Type % reduction of particulates
N95 99
SURGICAL MASK 74
HOMEMADE TEA CLOTH MASK 58
Also, the Elan Musk companies delivered 50,000 N95 masks to a hospital today.
