Masks will not save your life, masks are only about 85% effective if used in a medical hospital environment consistently the entire time. In our everyday environment, and just the allowance of human error, we are lucky if masks help even 50%.

Hand washing, hand washing, hand washing. And not just after the washroom either.

Wash hands when you wake up, before you brush your teeth, before and after you eat, when you transfer environments (like coming inside after being outside, or changing into another office building at work), after you drive, ESPECIALLY after handling money or credit cards, and after a long day behind your desk typing, before you go to bed and then we return to the start of this list in the morning ;)

^ that's a lot of hand washing, and I guarantee people are not doing it right. That is what will save lives.

(Not trying to diss you, you are at least trying to help, I am just trying to educate about handwashing)
