I had read that the recommendation is to use FFP3 masks. I am curious does that recommendation come from clinical testing or simply because such masks are theoretically better because they seal better and have a much higher efficacy in blocking small particles? (I am not in any way knocking the recommendation just curious how such standards come about. For example is FFP3 proven to be much better than FFP2 or is it just that it seems a wise precaution to use a more efficient particle blocking masks.) Either way I am glad that I dont have to wear such masks and all the other PPE all day - it must be very uncomfortable and draining after a long period.The general concensus within medics is that the surgical masks aren't great. For AGPs, we use FFP3s.
I feel surgical masks being used and their effectivness should be in context of how they're used. For example, anyone using surgical mask use in China as an example for how effective it is should take into account their PPE is significantly better than ours in terms of quantitiy.
