The GravityWorks Pump-Free Water Filtration System delivers the same fast, pump-free performance of the revolutionary CleanStream microfilter, yet with even less weight and more ease. Using advanced, Hollow Fiber technology and a little physics, it allows you to collect, transport, filter and dispense water, easier and faster than any other system available. An all new filter housing and streamlined Clean reservoir shave two ounces off an already wickedly light filtration system, and a straightforward, modular design presents customizable options for further trimming weight on ultralight journeys.

    Comments about Platypus Gravityworks 4L Water Filter:

    I used this on a backpacking trip on the AT and it is hands down the best filter. I have used most filters and for ease of use nothing can come close to this. Having four liters helps when you are in larger groups and or don't want to make a second trip to get more water. Love the fact you can disconnect the filter and dirty bag and use the clean water bag as my hydration in my pack. Big advantage is the clamp that lets water out like a garden hose. Which means you can cool down on a hot day. Highly recommend this filter!!!
