This is the bottle that will become your charcoal and sand filter.

Make a water filter out of charcoal and sand.

To use the filter pour water into the bottle and let it drip through the hole in the cap. The filter is still effective without rinsing but it will reduce the filter s lifespan. This will be the final barrier before the water comes out clean. Rinse the gravel sand and charcoal to remove unwanted dirt and silt from the materials before they are packed in the container.

A diffuser plate which acts like a strainer should be set an inch or two above the top layer of sand allowing room for the water to sit after you pour it into the bucket. You should have enough crushed charcoal to fill your cylinder up about halfway. Fill the bottom third of the bottle with activated charcoal the middle third with sand and the top third with gravel.

If you don t rinse first you will definitely need to run a few gallons of water through the filter before even attempting to use the water for something potable. With the cap still on the water bottle take your knife and twist a small hole in the cap about an inch in diameter. Take your cotton ball and push it tightly against the cap.
