Results so far: (rolling corn right now)(just got them before I began)
New plain disposable mask: fine until the rubber band wears out(not very long) or the foam on the nose, as long as it doesn't slide. Update: once it gets damp, it doesn't work.
New 8511 disposable mask: better than the plain one, but it feels like the shape is made to seal better. Valve doesn't open for me, unless I'm shoveling or panting/breathing through my mouth. Elastic instead of rubber(or at least braided, higher quality. update: like before, once it gets damp it begins to fog up my glasses.
Mask with screw on filters (3M 6291), seals the best, but not perfect, depending on how you put the straps. I think I'll also get a cartridge one to try, as the screw on filters seem like they go on a little too hard(as in they may rip)
Powered air hood(3M breathe easy): currently can't try as the rechargable battery was dead, so it's charging. You have to hunt to find filters that are affordable it seems, but I found a set out of souix falls SD for 25 each(takes 3)
I'll keep updating this as I will try them tomorrow with the cabless/open station tractor and feed wagon, also will try them cleaning out the shredder(Vermeer BP8000) and will try them shoveling out, and vacuuming bins, and if I remember, when it is -40 again (when I had the most trouble).
