Plastic water bottles are damaging the environment so a concerned entrepreneur developed a filter that lets you make mineral water called the WaterBean. WaterBean is a tube-like filter that can be inserted into any bottle to purify water. The filter uses natural coconut carbon to purify the water around it.

All you have to do is pop the WaterBean into a bottle to enjoy clean mineral water. The device expands and removes impurities while adding minerals that your body needs. As a result, you can stop buying bottled water since one WaterBean is able to filter 280 bottles of water. When you've filtered 140 liters of water, you can easily snap the WaterBean open and change the filter bags.
