"The DIY cloth masks aren't really for preventing you getting sick (better than nothing, but only about 50% protection) - it's about everyone not spreading the virus even if they feel fine."
If your mask is 50% effective in holding your crud in, and my mask is 50% effective at keeping your crud out, then that means that BOTH OF US WEARING MASKS raises the overall effectiveness to 75%. For both of us. Still not as good as N95, but I would say that is substantial.
