If you end up on the go without a water filter, you can save the day by making one. A soil filter is an excellent way to filter out impurities. While not as fancy as a commercial filter, it will get the job done so you can drink water during the emergency situation.
You don’t need much for a soil filter. You need to have a container, a shirt or another piece of cloth, and some soil.
Put the shirt over the container’s opening. Then, put the soil on top of the shirt. Just pour the water into the container. You do need to repeat several times until the water is clear. Since this is not as powerful as a commercial filter, it will take several trips through the filter to work.
If you do not have access to soil, you can replace it with sand. Both will do a great job in filtering out impurities.
