How do you filter dirty drinking water?

To filter dirty drinking water, start with a sediment filter to remove visible dirt, sand, or rust. Follow that with an activated carbon filter to get rid of chlorine, odor, and some chemicals. For deeper purification, a reverse osmosis system can remove finer contaminants like heavy metals and dissolved solids. If there's a risk of bacteria or viruses, adding a UV purifier helps disinfect the water. The right setup depends on how dirty the water is and what’s in it.
