Wellspring-G is a portable water purifier with a hanging bag design which can also be attached to a bucket according to users need. The system works on gravity to filter contaminated water through a 3-step filtration process which induces; DF, Activated carbon filter, and Hollow fiber membrane. These interchangeable DF, activated carbon and hollow fiber membrane filters are responsible for the removal of large suspended particles, toxic organic herbicides and pesticides and bacteria, and protozoa up to 99.999%, 99.99% respectively. The life of the filter is increased through repetitive backwashing with a syringe every once in a while.
