Water Purification is an important item for hikers, a great companion for adventures where clean and drinkable water is hard to find.
Generally speaking, water purifiers are designed to remove or deactivate waterborne protozoa, bacteria and viruses from the water you are treating. Traditionally, backcountry water filters remove waterborne bacteria and protozoa, but have been unable to remove viruses, therefore, UV light, chemical treatments or boiling were required to deactivate viruses by scrambling their DNA or killing them. Today, however, new advancements in mechanical pump purifiers provide a convenient option to physically remove bacteria, protozoa and viruses quickly and easily.
