Platypus took the already fast and easy-to-use GravityWorks™ filter system and came up with this smaller and lighter 2-liter version to fill your water bottles on backcountry adventures.

  • Features

    • System includes a 2-liter dirty collection reservoir, GravityWorks filter cartridge, universal bottle adapter and hoses
    • Fill the dirty collection reservoir, hang it above your water bottle and let gravity carry the water through the filter and hoses
    • Bottle adapter fits Platypus and most Nalgene, MSR, Sigg and Klean Kanteen bottles (sold separately); also attaches to most hydration reservoir shutoff valves and tubes
    • Hollow fiber filter technology offers a high flow rate of 1.5 liters per min.
    • Filter physically removes particles, protozoa, and bacteria down to 0.2 microns in size, including giardia, salmonella, cryptosporidia and others
    • Unfiltered reservoir features a quick-disconnect valve that automatically shuts off the flow of water when hose is disconnected
    • Shutoff hose clamp on the clean water hose allows on-demand water control for filling bottles; clamp also shuts off the system when not in use
    • Clean the system by simply holding the filtered-water container above the unfiltered-water reservoir to backflush the filter
    • Taste-free reservoir and silicone hoses ensure great-tasting water
    • Weighs only 9.5 oz.
