Well I purchased what was a really good “powered dust mask” and tried it out. “Powered” means there is a fan that draws in filtered air so that is all you should be breathing. Now the mask seemed to work well indoors however when I tried it in my shop it did not seem to work as well. To me it was very hot and as I perspire a lot it was uncomfortable and I was afraid of moisture on the little motor. Also it seemed to hurt the bridge of my nose after a short time. The short of it was it was not going to work for me. The very nice store (not named) took it back with no issue.
At this time I am still several weeks from really being back in the shop and then only for short periods. YES this stinks. One day at a time and we will get it figured out.
