By TB mask, do you mean the kind they show people in China wearing?

I'm referring to the 3M N95 mask. Looking at the pictures of Asians wearing masks I suspect they are wearing surgical masks. They protect against most bacteria. The N95s are a bit more substantial and don't carry the creases of the typical surgical mask.
