Jonas,
I work in a machine shop where we occasionally do grinding and welding. My sinus can't take this environment for even 10 minutes without acting up. I've found a dust mask made by Moldex that works well, and it fits under a welding helmet. The description is Molex # 2310 N99 Welding Respirator. I get mine from Gemplers.com . These probably aren't as good as a fresh air respirator for long exposure, but they are a lot cheaper and better than nothing.
