How to make a water filter with certain materials?
2L bottles scissors nylon screen or thin strips of paper clips rubber cheese cloth alum (potassium aluminum sulfate) plastic balls of fine sand, pebbles and gravel up cotton Two other materials approved for use in 2L bottles scissors filter fine nylon sieve or cheese cloth rubber bands paper clips alum (potassium sulfate, aluminum), cotton balls, pebbles, plastic wrap sand gravel and a maximum of 2 other approved materials for use in also like to know the filter layers of materials.
The only additional material you want to use activated carbon, a carbon filter. Basically, it is coal that has been crushed and pulverized. This is not the charcoal is obtained to shop, but the type of coal that remains after a fire. Cut the bottom of a bottle with scissors. Invert the bottle and cap with a ball of cotton mouth. Then, from the bottom, fill the bottle up half way, starting with fine sand, coarse sand to pass, then a layer of coal. Add another layer of thereafter gravel, then pebbles. Once water is added, things should be well filtered enough. I would not recommend drinking without however. A pump filter for camping is not very expensive these days, and water can be obtained from those who are certified as free of anything nasty, but the virus. This filter will surely give a better water, and give themselves to boil water for some uses, but is still far from assured.
