Platypus takes the hassle out of getting clean water on any journey with the GravityWorks 2.0L Filter System, bringing the speed of gravity filtration to a compact and ultralight system, perfect for solo adventurers and small groups. 

Offered in two models: the Complete Kit and the Bottle Kit, both kits feature a 2.0L Dirty collection reservoir with Quick Release fitting, hollow-fiber filter, hoses and a patent-pending Universal Bottle Adapter. The Universal Bottle Adapter is compatible with most water bottles, and also allows users to filter directly into hydration system drink tubes, re-filling reservoirs without needing to remove them from packs.

"The GravityWorks 2.0L Filter System simplifies outdoor water filtration. It’s easy; scoop up the dirty water, attach the appropriate adapter,  hold the dirty bag above your hydration pack or bottle to quickly filter water directly into it," said Erik Flink, division director of Hydration and Water Treatment at Cascade Designs. "It’s incredibly fast, easy, is field maintainable with a four-second backflush to clean the filter and works with your system, the way you want it to."

The Complete Kit option adds a 2.0L Platy bottle with push/pull cap adapter  This adapter also has an insert that works directly with hydration systems, letting customers filter directly into most shut-off valves without removal from the pack. All options allow the user to backflush in the field in just a few seconds, ensuring trouble free reliability for the life of the filter.

Hmmm... maybe someone hasn't thought through the physics... You're better off having the filter as low as possible (i.e. at the collecting end), to exploit the increased hydrostatic head, thus pushing water through the filter quicker... With a bit of luck, you can probably fix this by swapping the short and long tubing sections around. Unless there's something very cunning about the filter that means it works better with a low HH, or breaks if the HH is too high, but that wouldn't give much design margin.

or so as not to stress the pipe connections? looks like a copy of MSR though.
