The Earth moon filter is designed to pick up water from the ground with a spout. This spout can be access with pushing a triangle button on the side of the box filter. Also by pushing the triangle button it will close the spout and prevent the water or anything that is caught in the water from escaping. Then once the water is in the box it goes through a regular water filter system with coal, sand, and gravel. The water system is connected in a circular container as you can see in the picture it is to the right of the purple box. After the water goes through the water system it can drip down into a slot that is made for the water. The slot can be accessed on the side by pushing the circular button.
