The mask are meant to protect people from you. That’s why when people choose not to wear one in public around you they are assholes. It’s all fun and games until someone close to you dies of Covid or becomes sick.
Unless you have an n95 or the one the cops, firefighters, and medical people use, your not fully protecting yourself at all. It only has a max use of 8 hours though. Last I saw a ten pack is 200 dollars if you want one delivered from Atlanta.
I won’t buy a mask if it’s shipped from China. Defeats the purpose.
