"you never know when the person next to you is going to have that persistent wet cough that won't go away..."
"Used the cheaper 3M mask without the valve and had less reaction to the environment than this one."
"Issues I have are one, my beard (it does say in the manual that it doesn't work with them), but the way I keep mine trimmed and shaped it still works enough for just pollen and other larger particulates, no promises for anyone else's beard."

"you never know when the person next to you is going to have that persistent wet cough that won't go away... and they don't have the good manners to cough into a handkerchief or their sleeve... which happened to me on one of the hours long flights I was on.""The vent on the front is fine, works best if you breathe out through your mouth and kinda blow into it, makes you sound like Darth Vader but it does in fact cool things down significantly. Issues I have are one, my beard (it does say in the manual that it doesn't work with them), but the way I keep mine trimmed and shaped it still works enough for just pollen and other larger particulates, no promises for anyone else's beard... Took me three days to shape it to something that worked, and I have to wear it so high on my nose that it begins to interfere with glasses."
