Pete, you should look for smoke goggles. These are sealed, thermally rated and are impact resistant.

The purpose of the goggles is to stop your eyes being affected by smoke and very fine particles (as well as larger particles and debris which may hit you in the face).

You can purchase them form fire fighting suppliers.

It seems to me that there are only limited options for air way protection. From what I read it seems to me that the hood style probably offer the best all round convienicnce and protection for EDC ? Certainly a lot less fiddly than a maks and goggles.

Remember that most people who perish in building fires are actually overcome by fumes (gases) from combustion of man made materials, rather that "smoke" or other particles.

Also by protecting your vision (goggles etc), you will be better able to exit a hazardous area.
