Use these Cool-Flow N95 respirator masks for dusty work

These 3M Cool-Flow respirator masks have an exit valve that doesn't filter exhalations so they don't work as Covid masks, but I use them when I sweep, sand, spray paint, or work in a dusty area like my attic. They are comfortable and they really help me from having a sneezing fit. My daughter uses them for her art projects, too. Amazon even offers a subscription for them.
