How does anyone know that masks work?
There have been studies and there is also proof in the real world.
one study followed community transmission of SARS in Beijing. It found that consistently wearing a mask in public was associated with a 70% reduction in the risk of catching SARS.

It really makes sense just thinking about from a common sense standpoint. filtering the air you breath in will stop you from breathing in junk you don't need. And likewise, a sick person wearing a mask will keep the virus within their mask rather than blowing out all into the air around them.
