In order to make a water filter, you need to list things appropriate in an order of size.
(Decreasing in size)
Insect net-->marbles--> Pantyhose-->metal mesh-->sand-->gravel-->coffee paper
What you have to do is use the gravel as container, place material in it as the largest size(insect net) is at the top and the smallest size (sand) at the bottom. At last place the gravel above the coffee paper (make it as cone shape like when you place filter paper in a funnel) to be the final bottom filter. Finally.Wrap the whole thing with towel and tighten it with rubber band will do.Source(s): Myself
