This is the bottle I have and have used extensively in Ecuador. It is easy to use and carry. I like the fact that it is also viralcidal. The only problem I had was at the X-ray machine at the airport, the filter portion itself, shows up as a very dense item, which the screeners then check to make sure it is not one of the prohibited items.
I carried the same bottle when I flew to Utah for a few days of hiking in Zion National Park a couple of weeks back. The exact same thing as you describe happened to me on the way back. Once they looked at it, they had no problem with it, but it was funny. Interestingly, I carried the same bottle on the way up, and they didn't stop me.
