This video shows you how to make your very own water filter.
1. 20mm PVC pipe for upper section larger debris.
2. Small wad synthetic fiber inside the pipe as a pre-filter.
3. Another 20mm PVC pipe filled with charcoal pellets inside.
4. A coupler is between the two pipes with a plastic disk inside.
The disk separates the fiber and charcoal and keeps the charcoal in place.
