But these valves are meant to make breathing out easier, right? while
using the rest of the mask to filter the air that comes in, right? It

aid in reducing spreading.

Most masks are almost worthless. The n95 masks are made to work in a
contanimated area. They are to keep things out of you and not what you
breath out. The virus particals are too small to be filtered going into
you.

The home made cloth masks soon fill up with the moisture and then become
ineffective.

and drug laws. Many are on the books, but it is very easy to get the
illegal drugs and guns are easy to come by illegally.

Wow, that means Pence is smarter than you are. Scarey, huh?
