Making your own water filtering system

Take a container with a hole in the bottom. Add a few inches of 1/2 inch stone. On top of that, add smaller stone, on top of that, even finer stone, on top of that, even finer, on top of that sand.

Now, just run water through it from the top! (Hey! it worked 100 years ago and sounds like it costs nothing!).

This is reasonable for filtering out dirt and similar debris (assuming you start with clean, sanitary stones and sand). It's entirely ineffective against dissolved chemicals or microbial pathogens, or nearly so.

In the US, the public water supply is almost universally safe to drink, so a sand filter might be an appropriate choice. There are plenty of simple commercial filters available that would do the same thing just as well. In a place where the water is unfit to drink (as in it will make you sick), neither of these would be at all appropriate.

Maybe this will help, read this page.

Unless you have a problem with the water supply, just the external charcoal filter should be enough. Just change the filter occasionally.
