This perhaps?
Follow the link and scroll down. You’ll find a couple of links to study reports. One of those links is the one that you’re looking for.

What Are The Best Materials for Making DIY Masks?

Dish towels seemed to work the best for a DIY mask. Paper towels not so much.
Thank you. Yes, that’s the one.
Thank you.
Oh, if you really want a really effective paper filter, vacuum cleaner bags are really good, but really hard to breathe through.
I like at least a folded facial tissue in case I sneeze or cough inside the simple homemade ones. Banadanas with rubber bands. Don’t waste money on pony tail holders, NOT longe enough, doesn’t stretch as much.
The paper towel was just the liner inside a cloth mask. In the video it was said the paper towels were the best for keeping the virus in or out.
i read that the SARS virus was 1 nanoparticle (or was it .1 - can’t remember now-) but also read that typical masks don’t stop particles that small- none of them do- except for the really secure chemical filter ttype masks that are near impossible to breath in-
I suppose masks might filter out a small % of viruses that small, but I think most of the particles are getting through- but i suppose even a reduction of chance to 1/3 would at least be something- but if sneezing and coughing and just talking spew out clouds of virus, and most make it’s way through a mask, what god is wearing the mask really? there will still be a cloud left behind that folks will walk through- even if it is a reduced cloud- it seems that wearing the masks only slightly reduces the chances- Better than nothing? I guess- but still, in a room full of people, many particles are making their way out into the air if masks don’t stop particles that are 1 nanoparticle small or smaller- nooen knows how small the corona virus is yet- -
The two or three layer fabric masks with a filter pocket, with a folded paper towel inserted in the filter pocket will be about 80% effective. This is about as effective as we can get with homemade protection.
I would not rely on a mask made exclusively from paper towels. It won’t last and it won’t seal.
The masks I made for my two daughters who are a nurse, and a director of food service for major hospitals in heavily populated areas:

woops- meant nanometers, not nanoparticles doh!
Go watch the you tube video using toolbox brand shop towels. A company is making a better constructed version but has tested them to almost n95 level.
I have been making these at home but adding a 3m at filter. Very breathable and much higher filtration than any of the other homemade masks. Plus they are cheap to make.
