Dehydration can kill someone within a span of less than four days. So during emergencies getting water is more important that getting secure, safe and clean water. Contaminated water kills and sickens millions of people today. Therefore, building an emergency water filter can save your life and others during a crisis situation.

How to build an emergency water filter?
To build an emergency water filter follow the steps below:

• Arrange for charcoal from somewhere
• Crush the charcoal into fine pieces
• Get a container or make one such as can or bottle
• Pierce the bottom of the container with a number of holes
• Start making your five-layer filter
• Cover the bottom layer with leaves, grass, cheesecloth or coffee filters (should b nearly one-sixth of the height of the container)
• Add another layer of soil or sand and pack it down which should again be one-sixth the height of the container
• Add another layer of charcoal
• Add a layer of soil or sand but do not pack it down this time
• Add a final layer of coffee filter, leaves or grass
• The container being now full pack down the top two layers so as to form space for raw water to be poured into it
• Pour raw water inside the filter
• Drink the filtered water that trickles out from beneath

In emergency situations, such filtered water is ideal to drink. However, you can also add purification tablets to do away with the bacteria and viruses which are not confirmed to disappear with this process of filtering.
