As important as water is, I would not skimp on it.
Yes, iodine works, but I, being allergic to seafood, cannot use it. The little sawyer units are so small and light, with huge amounts of capacity, it would be difficult to not try and find a pocket to stick one in. Both I and my wife have one.
I do have a katydin, the pocket microfilter. I purchased it before I knew of the sawyer. Expensive, but an awesome unit.
I kind of decided to skip uv, as it always requires a power source, and takes a little time to be sure. Not that it doesn't work, just didn't seem a good fit for us.
