Answer 1

I’ve only used iodine tablets while backpacking, and as long as you wait long enough (an hour or so) you should be able to drink the water. I understand that the iodine kills the bacteria and cryptosporidiosis cysts. Just make sure to get the threads and cap wet with the iodized solution to prevent cross contamination.
