There may be no time, and if the earth flips, there may be no way out of the bunker. Or, it will crush anyone inside.

depends on what kind you have, and what the threat is.. for some threats you can just buy special filters.. sometimes, for something like a window unit, or removeable system, you can just take it out, and seal the hole with plastic. others, like central units, just sealing the whole thing with plastic and duct tape, should be enough. but of course you do realize this means no fresh air...(as you can't run the systems)
