What type of respiratory protection should I use with my bench top blast cabinet? The cabinet contains most of the dust but I find that some dust still escapes one way or another. I use glass beads mostly but also aluminum oxide. I definitely do not use sand. I have a dual cartridge half mask that I have been using but reading the instructions I found that it is not recommended for any type of abrasive blasting not just sand blasting. What respirator should I use to protect me from this fine dust or should I even be worried about it since I’m not using sand or silica to blast with? I just don’t want to have respiratory problems down the road.
