Vapur MicroFilter $69Essentially a foldable water bottle with removable straw that kills 99.9 percent of disease-causing bacteria and protozoa, the MicroFilter is one of the lightest and simplest water filters around. You simply fill up and drink. (Note: you have to draw pretty hard to get a good gulp.) Great as a just-in-case filter when traveling or backpacking.
