2) Also some people have a vented premium mask, which isn’t good for stoping aerosol exhalation, but another mask on top of a vented one can still allow its use.
3) I personally don’t think double mask is needed unless you can’t distance, indoors, or interact with a lot of people in places where many don’t mask. Then I have to take matters into my own hands and double mask in high risk settings. And I usually keep my sunglasses on.
4) Personally I find the South Korean KF94 very comfortable. The KF94 creates a bigger gap in front of your mouth to speak clearly. And I sometimes forget I’m even wearing it because it doesn’t touch my lips or corner of my mouth.
