But a mask like this is for extra wall of protection when social distancing. Certainly it’s better than nothing or a scarf. It’s also cheap and affordable. I think it’s clever! no you are right.

I have read rhe reports of using coffee filters and also hepa vac bags as filters. Hepa is the best, however most contain fiberglass which can be harmful if inhaled. The other issue is breathability. It may be possible to find a way to make a mask as effective as surgical masks, but it has to be breathable.

They have to do this because if someone dies because they breathe in fiberglass, i can only imagine the lawsuits they could face. High grade cotton material that has tight threads are good for home made mask but still cannot be considered medical grade.
