The Platypus GravityWorks Water Filtration System provides pump-free filtration for groups and basecamps, that delivers 4 liters of filtered water in just 2.5 minutes without work. Using two 4-liter reservoirs (one dirty, one clean), this ingenious system uses Platypus' Hollow Fiber technology and gravity to filter up to 1.75 liters per minute, with a filtration lifetime of 1,500 liters of water. The GravityWorks Water Filtration System is ideal for providing drinking, washing, cooking, or cleaning water for large groups.
