Ok were gonna make a filtration system out of any materials that you can find, and you can only use 1 coffee filter and anything else. We can't use pre-made filters sutch as a fishtank filter. And it has to have 3 layers of filtration, any ideas?

use the activated carbon pellets if you plan on drinking this stuff, but for clarity and cheapness the sand/gravel method will work.

One obvious filter material is charcoal. You might put a sand layer on top to catch any coarse debris without clogging the charcoal. That should catch most filter-able stuff.

this is an old one, stones pebbles then sand at the bottom,
three sizes of material. ive seen it done . murky water in the top, comes clearer out the bottom. you need a container or tank with a tap or valve at the bottom to release the clearer water. ,that you pour in the top

Sand, crushed shell and then the coffee filter

Try layering activated carbon and cotton balls.
