PUT IN CAR  TOOK AWAY SOME ODOR
Seemed to work in the smoke odor car.  Had a friend who doesn't smoke say she can't smell the cigarette smoke at all.  It says to let them re-charge every 30 days outside in the sun.  I haven't done that yet.  Another room had a funky smell from a dead mouse I found.  It eliminated that odor.  So it seems they do work well.
