PUBLIC WATER FILTER is a water filter and UV sterilizer that does not require an external power source. It can be used in disadvantaged areas that are difficult to get water, and where the water is easily contaminated by bacteria and sediment. PWF provides the main material, filter bucket, and rotating UV light module to improve water pollution, reduce the incidence of disease and death, and enhance local life quality in the form of a combination package. Users can join the local natural filter material to build the PWF device and filter the water resources by rotating the PWF.
