I have made this mask to wear after I had trouble breathing in a KN95. It fits well and the vault of air allows me to breath without difficulty. ?? good for asthmatics?? I just fixed the slit closed in one mask and in another mask fit it with a third cotton layer filter. Both draw in when I breath but I have no problem. I am a woman but my husband with a big face and a beard can also wear the same mask. Maybe it's suitable for many face sizes. It was well worth the effort and I highly recommend the mask. If you don't sew the opening closed or insert a filter I think the risk of a single layer of protection front and center of the mask is not good.
Any time you stay inside in a crowded place or a place wher someone possibly was there hours before, you need an aerosol filtration level, that means both a tight fit and a good filter as insert (and nose wire, and good ties). The aerosol contamination is rated at 80% level more or less now in studies. For a comercial semi disposable, the Nanoqueen from Korea is as breathable as a surgical mask and rated FFP2/N95.
Thanks! Turned out great 😊.

Size M? Or for all sizes?👍👋👋😀
I have the same question
I made several of these last year. Very easy to breathe. The mask does not touch the mouth.
