Well, apparently no one here has any expertise on the subject; hence the
silence.

I simply googled: safe room ventilation, and came upon this page:

It discusses a ventilator meant to keep your safe room free of stale
air, odors, mold and mildew while you're not using it, but also has
links to a page featuring their Safe Cell, which keeps the air
breathable while the room is in use:

I haven't read up on the technology or anything.   And I don't know how
you would keep it powered up for *months* if you had to -- but you can
continue the research on your own.
