For attics, I concur whole heartedly.

A week ago, I had a small job and thought I’d just be up there for a minute and didn’t need to go get a mask.

I was coughing and had black snot for the rest of the day.

I would also add wildfires to your list, if I knew a mask that worked, as our air is so full of smoke in Idaho, that it is repulsive to go outside.
