I am conducting a search for better breathing/dust filtration. I spend a fair amount of time grinding bevels in old hand tools: axes, adzes, drawknives, plane blades....I use CBN wheels to do this grinding and worry about the dust created. I also occasionally run an electric lunchbox planer, bandsaw...I try to use Festool tools when possible, largely because of the vacuum system that works so well, at the point the dust is made. Better to keep the dust out of the air in the first place. I also apply finishes. I suspect the fumes created may require different filtration than dust. I am wondering if there are “masks” with switchable filters, one handling dust the other used for things that creat vapors.
I wear glasses and my frustration with most masks is my glasses immediately fog up. Not sure if I need goggles to fit over the glasses, which may protect the glasses and my eyes. I have been looking at a GVS Elipse P 100- 1/2-3/4 mask. Reviewers say it works well with glasses. One reviewer mentions switching out filters for dust vs vapors. They make a more expensive model that has eye protection too. Maybe goggles that can be added when needed?
Thanks for your ideas/experience/thoughts.
