Making a charcoal water filter is an excellent survival skill to learn, and it’s very simple to do once you know the basics. There are a few different ways to make a charcoal water filter, but they all use 3 basic filtration layers that include gravel, sand, and activated charcoal. 

The first layer of the filter should be gravel, which catches large debris like leaves and twigs. Then you want a layer of sand, which helps to separate the smaller contaminants from the water and trap them. 

In addition, a layer of charcoal is necessary to remove chlorine and other contaminants from the water. This is an extremely important step because it helps to prevent your body from absorbing harmful chemicals from the water. 

Activated charcoal is an extremely absorbent substance that is used for many different purposes, including removing dangerous impurities from water. It’s also useful as a medicinal product that can be taken to treat poisoning and bites from venomous animals or spiders. 

Charcoal filters are effective at removing chlorine, sediment, bacteria, parasites, and volatile organic compounds (VOCs) from water. They can also help to remove bad taste and odors. 

A charcoal water filter works by catching larger particulates and breaking them down into smaller particles. Once it’s broken down into tiny bits, it can easily absorb and remove all the smaller particles in your water. 

You can purchase activated charcoal at your local survival store, or you can make your own by simply heating up a piece of wood until it becomes black and ashy. The high temperatures of this process create cracks in the charcoal, which makes it more porous and adsorbent. 

This adsorption process also causes the charcoal to bind to many of the chemicals that are in your water. These molecules are usually in liquid form or chemical form, and they attach to the bonding sites in the charcoal. 

To make a charcoal water filter you will need a water bottle, a piece of bark, sand, and charcoal. Most survivalists will use a two-liter soda bottle, but you can also make one from a birch or cedar cone if you have the time and expertise to do so.
