you shouldn't be driving through puddles that cover the front
lower part of the bumpeanyway, and if you do you've be slowly so no danger at all of sucking a puddle up that length of pipe. I did the same on my LCR and never once had any water in the
lower part of the air box when examined after a wet drive, it didnt even suck up spray.
So long as you get the filer back in place to seperate it from the intake pipe you'll be fine, and stay away from 200+mm puddles (aka rivers) or at least take a canoe with you ;-)
