Does it have a hole that pops open for exhaling? If so, then you are only filtering while you breathe in and if you have COVID, you are exhaling all of your infection.
No. My N95 mask does not have the flap that opens for exhaling. So I am on the side of the Angels...hopefully...probably :)

Most are not. In fact, my P100 mask is not on the “good side,” but I exhale a lot easier.
