How to Purify Water

If you're ever out camping, or in a survival situation, it's essential to know how to purify water. This is a simple method that anyone could do, and does not require any fancy equipment. All you'll really need is a water canteen, close-knit cloth, another container, and a fire (or camp stove). I recommend collecting water only from flowing sources such as rivers whenever possible. Just do yourself a favor and avoid collecting water near, or downstream from, known animal homes.

What you'll need:

  • Water canteen
  • Close-knit cloth (like a bandanna)
  • Container
  • Campfire (or a camp stove)


  1. Once you find an ideal location, scoop the water while holding the cloth by the corners. Then bring the corners of the cloth together to form a bag and strain into a container. This will remove any dirt and other visible particles, though not all unseen elements that could be harmful.
  2. The easiest way to ensure water purification is to boil it. Take the previously filtered water over a fire or camp stove. If you don't know how to start a fire on your own, here's a good video to watch that'll teach you the basics.
  3. Bring the water to a rolling boil and let it go a full ten minutes before removing from the heat. Pour the purified water into your water canteen and allow it to cool. It's now completely safe to drink!
