I’ve got an unfinished basement and I have a basement level French door that leads to a concrete patio that I ingress and egress along with a set of stairs from the main level. I keep my atv and my sons’ atv in the basement. This causes a bunch of GA mid to get trekked in and out. It dries on the tires and turns to fine dust. I sweep it up quite often but still this fine dust everywhere. The reloading area is walled off with Sheetrock for the most part and seems to get the usual basement “stuff”. Humidity isn’t a problem as I have a dehumidifier that runs automatically is over 50%. As I was cleaning up today I noticed a bunch of dust, mostly around the tumbler and presses. I imagine there must be some lead residue from the cases and primer compound when deprimed. Anyone keep a HEPA filter in their gun area? Any benefit? Thoughts appreciated.
