I had a respirator that my dog chewed so I have to buy a new one for fiberglass sanding. The one I had before was overkill (full face mask its what I had) but I wanted to see what every one was using for sanding fiberglass. Is a good fiberglass mask from 3M enough or does it have to have cartridges? I asked the guys at the local shop but no one had a clue.

I prefer the cartridges, the cheapo dust masks don't do enough.

I just use the cheap 3m thowaways, but whenever im sanding I always set up a fan to blow the dust away the second it leaves the pad. Stops a lot of itching and keeps you cool!

Respirator not mask

I use the masks, but make sure they are N95 compliant and have the exhalation valve. If they are good enough to stop tuberculosis then dust should be no issue. That being said I'll probably buy a cartridges next time for a big project cause in the long run they last longer and are cheaper.
