Peer review of research sounds like it should be a conversation between equals. Instead, it can be patronizing, demanding and simply unkind. A group of journal editors thinks this should change.
We tested well-fitting cloth masks made from 16 kinds of cotton, on human participants, to see how many provided filtration comparable with a certified medical mask. Most of them did.
Are two face masks better than one? Adding layers of filtration by double masking is a way of using the masks that we already have, possibly to better effect.
Tout ce qu’il faut savoir sur le polypropylène non tissé, le tissu désormais recommandé pour servir de filtre dans les masques faciaux en tissu : ce que c’est, ce qu’il faut chercher et où le trouver.
Everything you need to know about non-woven polypropylene, the fabric now recommended for use as a filter in cloth face masks: What it is, what to look for and where to find it.
Les épidémiologistes ont passé en revue 25 études sur les masques en tissu. Voici ce qu’ils ont découvert sur leur efficacité, leurs raisons d’être et comment ils protègent – ou pas.
