Water Filters (Portable Type)

We're doing a review of 5 water filters that you can carry with you in a backpack or even in your pocket. As we have with the rest, we'll use the top reviews from Amazon using only reviews that have 100 or more reviews attached to them. These filter all claim that they eliminate over 99% of  waterborne bacteria but will not filter out chemicals, heavy metals or viruses, and will not desalinate water, meaning they will not remove salt from sea water. Do your due diligence and read the reviews. Click on the picture or the underlined brand name, this will take you to Amazon for more information.
