It could save your life

When you go on a camping or hiking trip, the most important thing you'll need is water. Water can be very heavy to lug around, though. Fortunately, nature often provides a number of sources of water. Unfortunately, not all these water sources are not fit for human consumption. That's where Portable Water Filters can help. They are about the same size as a water bottle. You just carry the empty water bottle, fill it up when you can, and drink from the bottle. It's a great invention.
