The whole idea behind the masks isn't to protect you, which it won't. It is to protect others if you are unknowingly infected and cough or sneeze. The mask is to significantly reduce your released aerosols that may carry the virus. It requires a very specialized mask to block viruses from coming in. The odor thing is basically correct regarding viruses. They are far too small to be filtered out by anything other than very specialized masks, that are in essence custom fitted, none of which are readily available to the public. So, if you think the mask is protecting you, good luck, but you are misled. They may help reduce spread from infected individuals to some degree, but even that is pretty limited.
