Utilizing Hollow Fiber Membrane technology (the same technology used in kidney dialysis), the UZ-1 filters over 99.9999% of the bacteria that cause waterborne disease. It is easily maintained by back flushing with clean water, requires no electricity, there are no consumables to buy, and no parts to replace. Simply drill the required holes in two 20L (5 gallon) buckets and one lid, attach the included bucket connector, filter, and water tap, and the UZ-1 is ready to provide clean water, with no additional operating costs, for up to ten years. It is a simple, effective clean water solution that is easily deployed anywhere in the world.
