a review of mask materials

I found this review of masks and the materials that can be used when making them. It might be of interest to some members here. The summary is most interesting:

"Making DIY Masks with Household Materials
Bottom line: Test data shows that the best choices for DIY masks are cotton t-shirts, pillowcases, or other cotton materials.

These materials filter out approximately 50% of 0.2 micron particles, similar in size to the coronavirus. They are also as easy to breathe through as surgical masks, which makes them more comfortable enough to wear for several hours.

Doubling the layers of material for your DIY mask gives a very small increase in filtration effectiveness, but makes the mask much more difficult to breathe through."

Here's a link to the article: https://smartairfilters.com/en/blog/...iWMkKM4C2OfCyU

Of course, I can't vouch for the scientific accuracy of the article. The manufacture of air filters and masks seems to be the source.

I love this link and find it interesting that dish/tea towels are on the list. Good luck to everyone as we find the best mask to cover up. The lady I bought masks from today said she is going through all of her tshirts and knows others seamstresses that are buying underwear for elastic,as there isn't much around her now.

Dish/tea towels

I just wanted to clarify in case anyone only knows about the soft fuzzy dish towels. There are cotton dish/tea towels that are smooth and tightly woven like a pair of jeans only more lightweight and no other fibers woven in. We used to call them flour sack towels. These all cotton towels actually filter better, but are harder to breathe through.btgey would be fine if you do not have a lot of activity, but they might be hard to breathe if you must be active.

So just to be clear, the home made masks are not the be all end all of keeping virus free. They help.

because something I saw (can't remember where) said no knits, which have larger holes.

DIY masks are cotton t-shirts
It's my understanding it should be a woven cotton material.

At first I cut up one of dhs thick cotton t-shirts and it was great. Then I bought a 6 pack at Walmart and they were much thinner. Dont buy Hanes for masks!
