I just looked up the Pristine and it was drops (maybe chlorine or iodine). Which I am not apposed to, I guess I have been softened by society and was looking for a filter as well. Get all the bugs out so I don't have a sequel to the movie ALIEN on my home movies.

I guess what I want is for a water biologist to accompany me on my trips / bug outs and make sure that I won't get sick. Or something like that. Like I said, I am open to ALL suggestions on this matter as I have so little experience with water filters.
