3M 6900 full face respirator filter?

[socalkid]

Hello,

Soooooo my Mama loves me and for my birthday she bought me the 3M 6900 full face respirator but Im not sure what fillers to buy. Ill be using it for all my grinding needs (g10, steel, wood, kydex, titanium, etc.). So what would you guys recommend??? Any other breathing safety information would be great.

Thanks,

Chris

I use the 3M 60921 cartridges on my half face respirator. I'm 99% sure they fit all the 3M respirators. They should block pretty much everything, but it's always better to grind in a very well ventilated area.

P100
is the desigination for the particle size filter.

VOC Volatile organic compound - has some activated charcoal in it as protection against solvents glues and acetone.

You can get them in combination as Drsuds linked above

For some round filter types, you can get snap over pre filters that are cheap and easily replaceable to protect and get longer life over the main cartridge.
