Dunno about OP; I have 3M 7500 masks (small/medium/large as appropriate) with 60921i cartridges for the whole family. They are also used whenever we're doing fine grit sanding, fibreglass work, welding etc. so everyone's used to them. (Helps that they're pink, for the girls.)

Also keep iodine tablets in your bugout bag. And a razor, masks won't do shit if you have more than stubble on your cheek.
