I didn't read past the first couple posts but here is my 2 cents. I bought a pair of motorcycle goggles at the Dollar store. They have a foam gasket. Not the best for durability but I have used them in my Jeep in a dust storm and they worked. I EDC a Buff & large bandanna that can be used for breathing barriers, but also have a couple N95 masks in all my vehicles. I have started to carry a Shemagh in my backpack. Not super excited about the look but the results are undeniable if needed.
