I too am sensitized to CA glue and epoxy fumes. Any kind of simple dust mask is a waste of time and money. Even the ones with the carbon filters are no good.
My solution is to have an extraction system. I use an inline fan like this

I also wear latex gloves anytime I work with epoxy. I am seriously sensitised to epoxy dust so am very careful sanding it. If at all possible I will wet sand and bag any residue before it drys out.
