  • GravityWorks filter combines the speed and utility of the original Platypus CleanStream™ gravity filter with less weight and improved durability
  • System includes two 4-liter reservoirs, 1 for unfiltered water and 1 for clean water; reservoirs have hang loops for easy in-camp use
  • To use, simply fill the unfiltered-water reservoir with water and hang it above the clean-water reservoir to let gravity carry water through the filter
  • Hollow-fiber filter technology offers a high flow rate of 1.75 liters per minute—that's 4 liters in 2.5 minutes!
  • Filter physically removes particles, protozoa and bacteria down to 0.2 microns in size, including giardia, salmonella, cryptosporidia and more
  • Unfiltered-water reservoir features a quick-disconnect valve that automatically shuts off the flow of water when the 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 clean reservoir above the unfiltered reservoir to backflush the filter
  • Reservoirs feature SlimeGuard™ antimicrobial treatment for taste-free performance
  • Platypus GravityWorks™ water filter system is compatible with Platypus Bottles, Water Tanks™ and Big Zip SL™ reservoirs, all sold separately
