I don’t bother filtering my water, because most of the places I travel have clean water available. Instead, I bring my insulated water bottle full of ice cubes through TSA.

Interestingly they don’t care about frozen water, just liquid water.

As soon as I’m through the line I go to a water fountain and fill it and now I have ice cold water.

    You could look into a purifier, but that's a lot of extra bulk. I did not know they didn't care about ice though, sounds like freezing water bottles before you go might be a decent solution as long as you can keep them frozen for long enough.
