I make my own face masks. I am not sure they are safe. My husband wears an N95 over and over again without changing it. It makes marks on his face that last for a hour after wear.

The company has a standard Safety disclaimer for legal liability reasons since they have not been tested for this purpose but It would sure be great to know if, when placed between layers of fabric, they are safe?

Many of my friends are sewing fabric masks; some designs include pockets to insert extra filter materials.
Some masks use fabric backed by fusible interfacing, thus 2 layers of interfacing plus 2 layers of fabric.
Additional filter materials (optional) include quilt batting (cotton, polyester, & blends are available), coffee filters, furnace filters, shop towels (synthetic), cotton towels, tshirts, etc.
As a quilter, I know that there are different fabric types, weaves, treatments, etc, even if you only test 100% cotton fabrics.
I am an alumnus of UMR in Ceramic Engineering.

Distributing a “study” like this during a pandemic without proper peer review is unethical. Using Twitter as a platform to spread this information without proper review is unethical

If sandwiched between two layers of cotton fabric ,is there any problem in using them for face masks? 3M Staes on their website that “they do not recommend altering their filters due to a lack of research”. If these filters are used to clean the air in your house wouldn’t the scaled down version to a mask also be safe?

Not sure if I am exlaining that well. They seem to made from the same material that hosptial bed drapes are made from, the non woven poly.

Brand specificity mention was Zep industrial towels.

The designer of the mask suggests using a paper towel, but I’m wondering what the filtration capability of this mask would be if it had a piece of Filtrete Healthy Living 1900 HVAC filter inserted between the layers.

Viruses are not able to survive for long periods of time on some metals.

It seems that we could mass produce some useful items now that are vital to our health.
Let’s do it- contact Bill Gates even to fund this.
