Many reputable studies show that it is effective to wear a mask.
There really is no debate on that fact now.
At the time I advised N95 masks or better. You can see an N95 Mask in the thumbnail above. Hardly heavy duty
and don't you think that the W.H.O. would be recommending N95 masks instead of home made ones if they were ubiquitous? Think a little next time.
