Are masks, the kind with rubber bands sufficient?  What about respirators?  I have heard that Cerium O is not a good thing to breathe without something to block that dust floating in the air.  I have one lung left from Vietnam, so I want to be sure to keep it functioning, of course.  All opinions are welcome.  I use the rubber band kind when grinding/sanding/polishing, and a Harbor Freight respirator when using polishing agents like CO / TO/ Linde A/ #61 Rapid Polish, etc.  I think this is important as all of you guys are rare and there are not a lot of us.

I use a 3M mask like this one:

3M(TM) Half Facepiece Respirator Assembly 6291/07002(AAD), Medium, with 3M(TM) Particulate Filters 2091/07000(AAD), P100

The disposable ones are lighter but they wear out quickly so the 3M is more economical long term.

I also had a big eye scare this summer when I was grinding without safety glasses. A particle grazed my eye and I was lucky it didn't go in. I now ALWAYS wear safety glasses. I got these and they are excellent:
