I just don’t think people realize these N95 masks were not intended to be used outside of negative pressure rooms. To wear them in public was never their intended purpose. Which is why I used to sort of laugh at Asians in Asia wearing them.
Yeah, but. Like a lot of things they work as well or better for some uses other than their original intent and design.
We have a small amount on hand because we live in a rural western area subject to smokey wildfires in many recent years. The N95 seal beats the heck out of surgical masks, which are more intended to prevent medical people from breathing droplets out and into someone's open surgery site than anything else.
