I'm baffled how one office spreading patently false information that defies logic and physics could be so effective.
Not using a mask as community will ensure that virtually everywhere is potentially contaminated and you are under a larger risk and at all times --not isolated to the moment when you remove the mask (which people typically do at a place where they can wash/cleanse their hands anyway).

How do you know they're healthy? That's the key, because asymptomatic cases are estimated to be the main driver of this pandemic by far. And it's only worsened by the fact that only few tests are available.
Wash your hands. Wash your mask. There aren’t enough surgical masks for healthcare workers and they’re reusing them after bleaching or exposure to UV. You can reuse a dish cloth after washing it.
Additionally, if a homemade mask were to become contaminated, repeated handling could put you and others at greater risk.
