When you’re out in the wilderness, it’s important to have a reliable way to purify water.

Whether you’re hiking, camping, or backpacking, you never know when you might need to drink from a river, lake, or stream. Fortunately, there are many easy ways to purify water so that it’s safe to drink.

In this blog post, we’ll give you different methods for purifying water in the wilderness.

1. Boiling

One of the simplest and most effective ways to purify water is by boiling it for at least one minute. This will kill any bacteria or parasites that might be present in the water.

2. Chemicals

If you don’t have access to a heat source, you can also use chlorine tablets or iodine crystals to purify water.

Just add two tablets per gallon of water (or follow the instructions on the package) and let it sit for 30 minutes. For iodine crystals, add four drops per quart of water and let it sit for 30 minutes as well.

3. UV Light

If you have a UV light flashlight, you can also use it to purify water. Just shine the light into the water for six minutes, and it will kill any bacteria or parasites present.

4. Filtration

Filters can also be used to remove bacteria and parasites from water. There are many different types of filters available on the market, so be sure to choose one that’s right for your needs. activated carbon filters are particularly effective at removing impurities from water.

5. Solar Still

If you’re in a survival situation and need to purify a large amount of water, one option is to build a solar still. This involves digging a hole in the ground and then covering it with a tarp so that sunlight can enter but not escape.

Place a container in the middle of the tarp, and weigh down the edges of the tarp so that they’re touching the ground all around the hole. The sun will cause water vapor to condense on the tarp and then drip down into the container below.

6. Distillation

Careful not to boil too long or at too high of a temperature) and then collect the distilled water that condenses on the lid.

7. Plywood Still

If you don’t have access to a pot or other container, you can also build plywood still. This is similar to a solar still, but instead of using sunlight, it uses heat from a fire.

8. Thermal Desalination Bag

If you’re near an ocean or other body of saltwater, another option is to use a thermal desalination bag. These bags are specially designed to remove salt from saltwater using only heat from the sun.

9. LifeStraw

The LifeStraw is a personal filtration system that allows you to drink directly from streams, lakes, and other bodies of water without having to worry about bacteria or parasites.

10. Sawyer Mini Water Filter

The Sawyer Mini Water Filter is another personal filtration system that removes 99.99% of bacteria and protozoa from contaminated water. It’s small enough to fit in your pocket, making it ideal for hiking, camping, and backpacking trips.


These are just some of the many methods available for purifying water in the wilderness. Be sure to choose a method that’s right for your needs and always purify your water before drinking it, no matter how clean it looks.

With proper preparation, you can ensure that you’ll always have access to clean drinking water while out in nature.
