If you have a 3m tc-84a-1299 mask - you've probably been told it's not good for the current COVID 'protection' being mandated.
Most people don't get it - but these masks vent your exhaled air, so if you have COVID - in theory you'll spread it.
I found out the 'hard way' when I went to a hospital wearing mine and they added another mask on top of mine! (They didn't want me to remove mine - just add theirs)
Anyway - I designed this simple vent block to stop the exhale from exiting the mask. It works.
Why do this? Well - maybe you're stuck or love your mask so much you want to wear it anyway? Who knows but here is a solution that should keep those around you safer.
In theory.
Anyway - I put a think layer of double stick tape between the printed block and the mask.
