- FFP2 masks must be worn in all indoor spaces that are not private areas, i.e. for all stores and for services provided in close physical proximity.
Why is that? I am not an expert on filtration and I doubt you or anyone sharing this forum is either. That does not mean we should not make our own personal decisions on protection either. If someone wants to wear a mask then do so, they should. I wore them frequently while working around heavy dust. I do know breathing in our own Carbon Dioxide can be very unhealthy.
I've also learned from those that have worked with filters that say not even the N-95 is able to capture less than 40 microns while the virus is much smaller. By this comparison the chain link fence to keep out the mosquito would not be too much of an exaggeration.
