Interesting theories, hears another one, maybe he's one of the few that realizes how useless a mask is. Corona virus is a nano-particle that averages .125 microns, the N95 mask (which no one can get) filters particles down to .3 microns in size. The homemade or 3 for a dollar masks that everyone is wearing won't trap most dust particles. Would you make a mosquito net out of chain link fencing?
