An interesting graphic I found of the average mask pore size, and the size of a typical coronavirus. Many agencies don’t want you to know this. I didn’t make this graphic, I just found it. By “disposable” mask I assume they mean the surgical masks. More studies that show masks cannot stop viruses. They work well for stopping bacteria but only for about 2 hours then effectiveness drops significantly.
