Does your face mask protect you or other people?

Should we wear face masks? We tell our children to cover their mouths when they cough, so when we cannot predict who may or may not have COVID-19, it makes sense to wear a face covering in public.

But not all face coverings are the same. They can be split into two broad categories: respirator masks designed primarily to protect the wearer and cloth face coverings that could be considered to act more as breath diverting devices.
