Intrepid,
Welcome to the fire, newguy! Any chance you could post a picture of your water filter? I'd like to see how much damage has occurred. You might want to call or write PUR for their advice. Iodine is VERY reactive stuff and so I'd be a little concerned about damage you couldn't see such as weaken plastic or damaged seals. Having it fall apart on you out in the woods would not be good.
Please keep us posted on this, it's very interesting.
