You're using the mask to protect your lungs from paint containing lead.Hello. I just realized that I was using the wrong mask for sanding. I was using a 3M 8210 N95 GENERAL USE RESPIRATOR. I am planning to get a better one. But is it bad that I used that one for like four hours spread over a few days, I am a little worried, Thank you.
repeated for emphasis?...and there's nothing wrong with me wrong with me.
