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.


Thank you,

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



Also, the Elan Musk companies delivered 50,000 N95 masks to a hospital today.
