I think you might have hit the nail on the head with atmospheric
pressure. I generally don't bother to run the coil here at work if
the atmosphere is damp because it has never worked as well (doesn't
seem to holdoff all that well), but I've never correlated that
with air pressure. Must look into it.
One final thought - we are surrounded by coast here and there
is often a salty mist around although I suspect, not in the building.
