I have a Pur water filter pitcher thingy. We use it at home for Satin and us humans. Whenever hedgie has to go to the hedgie-sitter, the filter/pitcher goes with her. The water at home vs at my mom's place (ie, hedgiegrammy) tastes very different. But, when filtered, tastes the same to me. And it's similar enough that hedgie hasn't had issues with it.
My vote is to just bring along a filter rather buying and recycling bottle after bottle after bottle after bottle of the water. A bonus is that you can have filtered water just like your hedgie if you want
