Water filtration may be mostly unnecessary, but water purification (elimination of gut-crunching pathogens) is another story. If you're in a true survival situation, taking a chance on drinking water that could have dangerous pathogens is probably not worth the risk. Every water source is different and carries a different risk profile (how far upstream, where the water is sourced, etc).
You don't need to buy anything to purify water. Oddly this article did not discuss the simplest method of all - just boil it. A steel, non-insulated water bottle works fine.
- dwyerm 9y agoYou don't even have to boil it, technically. Most pathogens die at a much lower temperature, given enough time. For what it is worth, our backwoods trip had us looking for clear, running water that had a small amount of green stuff growing in it, on the theory that if it wasn't killing greenery, then it wasn't killing you. Then, a treatment with off the shelf iodine tablets. No filtering needed. The iodine added an unpleasant taste, but I thought that was better than the gut-crunching alternative. http://www.who.int/water_sanitation_health/dwq/Boiling_water_01_15.pdf http://www.who.int/water_sanitation_health/dwq/Boiling_water...
