When you find yourself in a survival situation, you may not always have access to potable water. You may not have the chemicals or technological means to purify water for drinking. Boiling the water cannot remove the sand and different particles out, and this may adversely affect your health. The best way to survive is to filter water without using technology, relying on the resources available in the environment.

As the world becomes more concerned over the quality of its drinking water, the knowledge to filter water the natural way is considered an essential tool for survival. During emergencies, this knowledge can be handy due to the need for people to be careful of what they drink. Bottled water supply can always run out, as well as other sources of clean drinking water. If this happens, water filtering, combined with some water purification methods, can supply you with the precious liquid to keep you hydrated until the situation normalizes.

Key Steps Prior to Filtering Water

  • Gather your water resources.
    S2RSA0011 - 2.jpg
    When all remaining sources of sterilized water have been used up, the next thing to do is to scout for sources of water. At home, this can be from water heaters and toilet tanks. If you're in the wilderness, possible sources include rivers, streams, and other body of water. Collect as much water as possible. Do not consider using stagnant and/or smelly water.
  • Create a natural water filtering method. If the available water in the environment contains dirt particles, such as sand and other debris, you can use any of the following filtering methods to remove them.

Procedure:

  1. 1
    Create small holes at the bottom of a water container.
    The holes must be big enough for water to filter out, but not too large for the filtering materials to pass through.

Single Layer Filter

The method is basically the same as the multilevel filtering.

The difference is in the use of few filtering materials to suggest that there's no abundant supply in the environment.

Procedure:

  1. 1
    Drill a hole in the cap of the filter bottle.
    If there's no cap, poke holes at the bottom instead.
    Was this step helpful? Yes | No | I need help

  2. 2
    Cover the holes with a layer of cotton or coffee filter to prevent the filtering material from falling out.
    Was this step helpful? Yes | No | I need help

  3. 3
    Fill the bottle with enough sand or crushed charcoal.
    Was this step helpful? Yes | No | I need help

  4. 4
    Cover the layer with another piece of cotton or coffee filter.
    Was this step helpful? Yes | No | I need help

  5. 5
    Slowly pour water into the filter bottle.
    Let the water drain before repeating the process.

  6. 6
    Place the second bottle below to catch the filtered water.

Cloth Filter

If no filtering agents can be found around, you can use your clothing or any fiber instead.

Procedure:

  1. 1
    Secure the cloth material or fiber to the container.
    If the cloth is not large enough, tie the corners to pieces of sticks. If there are no sticks, just position the material on the top surface of the water container.
    Was this step helpful? Yes | No | I need help

  2. 2
    Pour water through the material to drain into the water container.
    If there's no water container, drain the water directly to the mouth.

How to Make Filtered Water Safe for Drinking

  1. 1
    Boil.
    S2RSA0011 - 7.jpg
    Filtered water may look sparklingly clean, but it can still be infested with microscopic organisms such as Giardia lamblia and Cryptosporidium, as well as bacteria like E.coli and Shigella. They carry diseases harmful to human beings. One way to kill these disease carriers is to boil water where they thrive. Boiling without using electricity can be done by making an open fire pit. Leave the water at a rolling boil for at least a minute before letting it cool down.

  2. 2
    Bleach.
    S2RSA0011 - 8.jpg
    When water cannot be boiled during a situation, use chlorine bleach to remove most of the harmful microorganisms. Read the product label and use an eyedropper to apply the right amount of chlorine to the untreated water. Wait at least 30 minutes before consuming the water.

  3. 3
    Iodize.

    An alternative way to purify filtered water is to add iodine drops. A quart of water requires two drops, and can be increased if the water is a little bit cloudy.

  • To improve the taste of boiled water, add a few drops of honey or lemon juice.
  • Add a pinch of ascorbic acid to chlorinated water to remove the chemical taste.
  • Change out layers of filtering agents for new ones after using them several times.
