Source Tube Kit + Filter

The Source Tube Kit + Filter turns (almost) any bottle into a complete SOURCE drinking system with water filter. Fill your water bottle without worry from any water source - the filter eliminates 99.99999% of bacteria and protozoa, a value above the recommended EPA value. Microfiber tubes block and neutralize harmful bacteria and protozoa in the outer walls. This guarantees your water is safe to drink. Thanks to its durability, you can fill your bottle with up to 390,000 liters from freshwater lakes, rivers and streams and drink it without adding weight to your luggage. You don't need replacement cartridges for your Source Tube Kit + Filter. The article is the tube + filter, bottle not included!
