Product Highlights

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.

    Likes: Got home to find my Platypus GravityWorks 4.0L Filter System waiting for me. Received it within a week from ordering. Not exactly having the weather to field test it, I decided to familiarize myself with it at home.

    Easy assembly, Markings are Clear, No way to mess up.

    Filtered 4.0L in minutes. Could actually notice a difference from Tap Water to Filtered. Can't wait to try it in nicer weather.
