For travelers and backpackers, water treatment is critical. Backpacking water filters and purifiers are essential pieces of gear whenever you’re going to be relying on rivers, streams and lakes for your supply. Backpacking water filters use a hand pump that can easily draw water from a variety of sources and are a straightforward option. Water treatment is equally essential when traveling to countries where water purity problems are known to exist. Water purifiers that use ultraviolet light protect the body from harmful microbes – including viruses – present in the water supply in some parts of the world. Ultraviolet water purifiers like the SteriPEN won’t alter the taste of the water and won’t require the use of chemicals to protect you from microbes.
