As long as you are staying in locations where you can trust the quality of the water the only down side to Activated Carbon filters is that you may still get some high mineral content water. Even major metropolitan areas can have T&O (taste and odor) episodes that can make the water water less desirable for drinking and if they use surface water, occasionally may have an issue with Cryptosporidium which is very difficult to remove without ozone treatment, RO or microfiltration.
