it's pointless to mess around with N95 if you haven't been fit tested. That means close shaves every day. A good analogy would be playing 4K video on a machine that can only render 720p resolution. You'll get a lot more buffering (discomfort) with no improvement in quality (proven benefit).


Improper fitting N95s are still vastlt more effective than proper and improper worn cloth masks, that’s due to the electret fiber charge :)


I love this thread.
