The Platypus GravityWorks 4.0L Filter System utilizes innovative Hollow Fiber technology to offer pump-free water filtration. Perfect for base camping or larger group backpacking trips, the GravityWorks 4.0L Filter System includes a 4.0L Dirty reservoir and 4.0L Clean reservoir.
The groundbreaking Hollow Fiber Technology used by the GravityWorks 4.0L Filter System enables it to efficiently and effectively filter 4 liters of water in just 2.3 minutes! Simply fill the 4.0L reservoir marked "Dirty," suspend it from a branch using the strong clip webbing, and allow gravity to filter the water into the "Clean" BPA-free 4.0L reservoir. The "Clean" reservoir disconnects for easy dispensing.
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 meets all EPA and NSF guidelines for the removal of protozoa, bacteria and particulates. It is NOT effective against viruses.
