Remember, Masks Are Only Needed If You Are Sick
We've been making some pretty sweet masks.
Some of my other friends are making some pretty sweet masks, too. Don't forget that these types of masks are really only meant to keep you from spreading germs, not necessarily to keep germs out. You would need a real hazmat type of mask to keep germs out.
A lot of germs are spread when you cough moisture droplets into the air, and these types of masks reduce that greatly. Let's say an inconsiderate sick person coughs on you. Well, that moisture may just land on your mask, and you're stuck breathing it in. That's the worst-case scenario.
Still, let's talk best-case scenario: wearing masks like this could keep your family and other people from catching whatever you got. Then again, you could just go cowboy and cover your face with a bandana.
