Referring to the medical-surgical masks we often talk about recently, if we refer to the BFE standard, the medical-surgical masks are BFE99 plus VFE30. If you can't filter the virus, it's useless, so isn't the medical-surgical mask completely useless?
However, this is not the case with BFE99. Viral particles smaller than 1 μm have a sharp decline in infectivity. Large particles are like sniper bullets, one fatal. And small particles are like a poisonous gas, low concentration has little effect, and high concentration is dangerous. Only when patients are very densely gathered in an enclosed space are small particles in sufficient concentrations to infect people.
For general daily protection, surgical disposable masks, BFE99 masks, and PM2.5 masks are all-sufficient, so for daily protection in general life, medical-surgical masks are effective enough. BFE 99 masks are also effective enough.
It is only necessary to put on an N95 or BFE99 mask when you need to go to the hospital, live in the same room with patients, or have to be in an enclosed space with a lot of patients.
Through the above introduction and analysis of the necessity of using BFE99, hope it helps you.
