Every time there’s a typhoon, water turbidity becomes a problem. Researchers at the Hsinchu-based Industrial Technology Research Institute are working to solve this problem with simple implements such as an umbrella that doubles as a water filter. After yellowish water is poured into this umbrella, it passes through a filter and come out clear and safe to drink. The umbrella contains ITRI’s latest water filtration system.Chen Jian-hungITRI ResearcherThis special device typically serves as an umbrella. But the tip also has a filter, so when you need water, you can pour it in and clean water comes out. Another tool that works as a water-cleaning device is this hiking pole. It comes equipped with a filter inside that can clean 1.5 to 3 liters of water each hour.Chen Jian-hungITRI ResearcherIf it only had a single use as an emergency implement, we thought it would be a waste, so we found a way to combine it with some other daily tools to make it more practical.The filters were put to the test using water in the mountains after typhoons passed. Now that they have been combined with other common items, they are available to help people enjoy clean water everywhere.
