PFBA is transported in rain and snow. That suggests that it sticks around in the vapor and condenses back into the liquid. There's no escaping it except to break it down, but that's the crux of the issue - the PFAS class of molecules are extremely energy intensive to break apart, which is why they don't break down naturally. Important to note that while the EPA says names acceptable level of 4PPT (https://www.theguardian.com/environment/2023/mar/14/epa-drinking-water-limits-pfas-forever-chemicals https://www.theguardian.com/environment/2023/mar/14/epa-drin...) for drinking water, they name that level out of pragmatism. They found health effects at every level, and the acceptable level is actually closer to 0. Also distillation is very energy intensive. A solar still makes sense if you need to do this a lot and live in a sunny place.
