I have a one-room building out back that's been closed up for a long time
and has taken on that characeristic musty odor that storage facilities
sometimes get. I've tried a window fan, but as soon as the fan gets turned
off, the odor is back.

Would one of those ionic air cleaners solve the problem?

Maybe. Charcoal briquettes might be worth a try. I have friends who have
used this method and swear by it ... never tried it myself. Not sure what
they do ... absorb the odor?
