Best bet is a respirator with activated charcoal AND P100 filter. Some of the nasty bits in wildfire smoke are volatile organic compounds and heavy metals. P100 takes out some of the first and much of the second, but with a respirator 3m you will get first class protection. Now they are a drag on your face, and it makes breathing more difficult; I just walk without pushing it when I have to exercise in smoke with the respirator. Not what you want, I know, but what works for me.
