I don't even have to look at the study to know it has made some really key assumptions that would not exist in real world use, such as:
the N95 mask has to be fitted to the face and worn tightly. It's uncomfortable and restricts breathing. Even trained people frequently demonstrate poor technique.
the N95 mask (any filter really) will become saturated at some point and must be changed. In the community, people don't change their mask every 2 hours or if they cough/sneeze/saturate the mask with droplets.
For those two reasons alone, every study that I've seen that has ever shown success with these masks in a highly controlled lab or clinical environment fails in the real world. Studies which test the masks under real world conditions always fail.
I will not comply with this garbage. I'm not going back to it. If you've got respiratory symptoms, stay home. If you have to go out and are coughing/sneezing/whatever, then wear a mask to control your own spreading of the disease. If you have TB, you wear the damn N95 and take your meds, regardless of what color they turn your pee. But for general use in perfectly healthy people, the answer's no.
