Mows4three 826 #1 Posted September 14, 2020 Hello and good afternoon all...! I have a 3M respirator but I’ve been using since about 1980. It’s the gray, two-strap mask that uses round canisters for filtration. It is literally starting to fall apart. The elastic is gone from the straps and the rubber face piece is beginning to disintegrate. I do a lot of wire brushing on rusty and painted metal. I do some painting, but primarily I’m concerned about the new grinding stones and flap sander abrasives I use when forging in my blacksmith shop. There’s a lot of good press out there on RZ Masks with replaceable filters and washable mask material. I’m leaning in that direction. Before I fork out some hard earned dough on the RZ Mask system, does anyone else have any ideas, suggestions or intel to share? Thanks! Dave 1 Share this post Link to post Share on other sites

If you are painting catalyzed enamel you don't want to use anything less than a respirator. 2 Share this post Link to post Share on other sites
Mows4three 826 #5 Posted September 15, 2020 Correct on the painting.... I’m looking for dust protection. Share this post Link to post Share on other sites
