I'm working with alot of fiberglass recently, making one off parts. I want to get a good filtration mask, dont want to breathe in that junk. Do you guys have any recommendations? Do you know of any sites that carry them?

 

Dude google. Good, big Ace hardware stores carry them and also the replacement cartridges. I'm sure Home Depot too.

6000 series halfmask.
