The ONLY mask that has any efficacy is the N95 medical mask.
It can filter out virus up to 95%
All the little masks that people are running around wearing don't do anything except stop "droplets" (liquid again) when you sneeze.
The virus itself is microscopic and isn't affected at all by the mask.

Here is the simple math and what are you missing logic !
Double layered cloth mask is about 60 % effective while exhaling and about 40% effective while inhaling.
Now look at a viral load of a factor 100 in a person next to you who has a mask:
His viral load while exhaling in your direction is reduced to 40.
Now if you are wearing a mask you may inhale only 40% of the load from a factor 40 which is factor 16 of the initial load.
So simple stated, if both are wearing a mask, the risk of transmission is reduced 5x or more.
