Poor drinking water quality is causes of many diseases,including cholera and diarrheal diseases.Clean Water Porter provides a low-cost solution for people's healthy drinking water.Inspired by the agricultural microporous clay irrigation,the cup is made by sintering diatomite,clay and calcium sulfateand can filter water automatically.It only needs to be placed in ponds,puddles,etc,under the action of gravity and water pressure,the water can be automatically filtered.At the same time,as the center of gravity changes,the orientation of the bottle will also change,so as to quickly give users a reminder of the amount of water stored.
