The best homemade filter is the grass filter (Allen). The grass filter is completely natural and resembles the natural process the most. A filter removes impurities in two different ways.

Chemical filtration is when water is passed through an active material that removes impurities chemically (Type of Filters). Soil is an example of chemical filtration. Soil is the most natural filter. Soil has its limits, but can purify water (Earth’s Largest Filter). Filters are used so that water is clean and drinkable.
