masks help primarily in a one way direction: you breathing outwards. that's always been the case and that's where it's helpful with asymptomatic cases. if you're infected and breath out, sneeze, cough, etc you limit the amount and distance.

in terms of protecting you they aren't entirely effective but there's a reduction based on materials and layers, which should be obvious considering it's literally less particles. wash clothes proved extremely effective when layered, to a degree of 97%, same as an N95.

now if you want to wear one or not that's a different story. by one i mean anything to cover your face, not just masks, as a multi-layered scarf is just as effective as some of the crap out there. i generally don't. but i at least know the logic and science behind it.
