How to Make a Water Filter

In an emergency, it is important to have access to clean water. If you are unable to find clean water, you can make your own water filter. This will help to remove impurities and bacteria from the water, making it safe to drink.

Materials Needed:

  • 1 empty plastic water bottle
  • Scissors
  • Rubber band
  • Activated charcoal (available at pet stores)
  • Gravel
  • Sand
  • Coffee filter

Instructions:

  1. Cut the plastic water bottle in half.
  2. Place the bottom half of the bottle upside down on a flat surface.
  3. Put a layer of activated charcoal in the bottom of the bottle.
  4. Add a layer of gravel.
  5. Add a layer of sand.
  6. Place a coffee filter over the top of the sand.
  7. Secure the coffee filter in place with a rubber band.

Your water filter is now complete! To use it, simply pour dirty water into the top of the bottle. The water will filter through the layers of charcoal, gravel, and sand, and will collect in the bottom of the bottle. The coffee filter will help to catch any remaining impurities.
