That applies only to lab conditions. No RCTs have found much effectiveness so far in real life.

  I'm sorry, but that is some absurd nonsense if we're talking about N95 masks and not surgical masks. You have been misinformed.

    The RTCs didn't find significant difference between N95 and surgical masks in hospital settings. How can a request for evidence be absurd?
