Folks— *DOUBLE MASKING* could be the safer way to go. Biden used a surgical + N95, while I used a KN95 + KF94 (South Korea made). Not only do each offer better filtration than cloth mask, but also in case one is a fake knockoff (lots fake KN95s) and saves mask longer. #COVID19

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.

5) UPDATE— read this new thread. We need to all upgrade to premium masks https://twitter.com/drericding/status/1353186978519539712
