This mask can be wear alone, or insert extra layer of filters inside, or use as cover for N95 mask. The vertical loop elastic adds more comfort for long period of wearing.
I am not good at video making, but just want to make this tutorial since many volunteers were asking how to make this kind. So, please forgive me with the edits and some not too good angle and lighting.
regarding the filter: it's 3M top grade 1500 air filter you could get from local Low's or Home depot or amazon. It's not fiber glass as someone concerned about this.
