|3 stage water filter|
cloth to be used for the filters. Fill the highest layer with grass or leaves to filter out big particles. Next fill the middle layer with sand to catch smaller particles and finally fill the bottom layer with charcoal from your fire to remove the bad taste, odor, and other impurities.Be sure to place a catch can under the bottom layer.
To use, pour water in the filter at the top layer and wait for it to strain into your catch can. This is a great method to make muddy or swampy water drinkable just remember to boil after filtering.
