Platypus GravityWorks Group Camping Water Filter System, 2-Liter;

The Platypus GravityWorks 2.0L Complete Water Filter Kit for camping, backpacking, and emergency preparedness is a versatile, adaptable water filter solution, compatible with a variety of hydration vessels, including hydration bladders and water bottles from MSR, Nalgene, Klean Kanteen, Hydroflask, Camelback, and more. Ultralight (weighs as little as 6.6 ounces in minimalist configuration), and packable to the size of a 1-liter bottle, it’s ideal for filtering water for 1-4 people while hiking, camping, or trekking. The replaceable hollow-fiber microfilter cartridge filters up to 1,500 gallons of water, and meets EPA and NSF guidelines for removal of 99.9999% of bacteria and 99.9% of protozoa, including giardia, cryptosporidium, E. coli, salmonella, and cholera. The water filtration system is easy to use almost anywhere, by scooping water from a lake, river, stream into the 2.0-liter dirty water reservoir, and suspending above a bottle or other clean water reservoir. Water flows through the walls of the bundled fibers at rate of 1.5 liters/minute, leaving impurities behind, without the use of pumps, batteries, moving parts, or chemicals. It’s also easy to maintain in the field, backflushing in just four seconds to clean and restore performance. The Platypus GravityWorks 2.0L Complete Water Filter Kit Includes a 2-liter dirty water reservoir, 2-liter Platy bottle, hollow-fiber filter, hoses, universal bottle adapter, push/pull cap adapter, and storage bag. Made in the USA.
