The secret ingredient in N95 masks (and surgical) is a very fancy modern material: melt-blown non-woven polypropylene.
This is what makes a paper thin surgical mask way better than a thick cotton one.
- richajak 7y agoTotally agree, that's said most people cannot get surgical masks anymore, not to mention N95 masks. If we can learn the lesson from outbreak happened before modern tech invented, world would be a better place. We cannot produce or easily buy nanotech material used for N95 masks. However we can use whatever materials avail in our house easily. If need extra protection, add 2 layers of tissue between mask and face. Do not touch mask when you are outside. Stay away at least 2m from any human being. Do not touch anything outside. Immediately take shower and disinfect youself with 80p alcohol at home. :) hopefully most of us will not get infected, I do not want scenario in movie like Contagion or World War Z to happen for human race.
