I don't trust plastic bottles, how is the Alter Ego different?

The Eastman Tritan co-polyester used for the production of the Alter Ego duo is BPA and Phthalate free on top of being a highly stable material that is now widely used by the water filtration industry. Moreover, the water filtration process in the Alter Ego happens at the end of the cycle and just before the water gets to the user’s mouth. Any contaminant that could still be in the water at that point is eliminated by our highly effective filtration technology.
