Redundant Water is a filtrator that can filter the dirty water. When we clean vegetables and fruits, a lot of water is always to be wasted. However, the redundant water totally can be used. A lot of water directly flows into sewer before to be processed. After days and months, more and more water that is not very dirty will be wasted. Redundant Water will solve this problem from the source, for the redundant water can be filtered and reserved at any time for direct drinking.
