Make A Water Filter Out Of Charcoal And Sand

Read on to learn how to make a filter out of a coffee filter and a banana peel.

Make a water filter out of charcoal and sand.

Take your cotton ball and push it tightly against the cap. You should have enough crushed charcoal to fill your cylinder up about halfway. It is a good idea to place a couple of inches of packed down grass or sand or another piece of cloth on top of the charcoal to prevent it from becoming displaced when you add your water. If the water runs rather than drips through the filter you will need to pack your charcoal tighter.

To use the filter pour water into the bottle and let it drip through the hole in the cap. 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. Rinse the gravel sand and charcoal to remove unwanted dirt and silt from the materials before they are packed in the container. To create a slow water filter diy using sand you need a bucket with a layer of gravel at the bottom an equal amount of coarse sand above it and a large amount of fine sand on top.

This is the bottle that will become your charcoal and sand filter. This will be the final barrier before the water comes out clean. 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.
