The Platypus GravityWorks 4.0L Filter System utilizes innovative Hollow Fiber technology to offer completely pump-free filtration. Perfect for family camping or base camp usage, the GravityWorks 4.0L Filter System includes two 4.0 liter reservoirs. Simply fill the reservoir marked "dirty", suspend it from a branch using the reinforced handles and allow gravity to filter the water into the "clean" reservoir.
The ground-breaking Hollow Fiber Technology used by the GravityWorks 4.0L Filter System enables it to efficiently and effectively filter 4.0 liters in just 2.5 minutes! The 0.2 Micron cartridge exceeds EPA guidelines and is completely field maintainable and long lasting, effectively filtering up to 1,500 liters of water (depending on water quality) before needing replaced! The GravityWorks 4.0L Filter System can be backflushed in seconds to clear the filter of debris and the streamlined, lightweight filter housing is durable and saves on weight and space.
NOTE: The Platypus GravityWorks 4.0L Filter System is effective against protozoa, bacteria and particulates. It is NOT effective against viruses.
