Platypus GravityWorks Water Filter - $89.93

The Platypus GravityWorks(TM) water filter delivers 4 liters of potable water in just 2.5 minutes without requiring a single pump stroke. GravityWorks filter combines the speed and utility of the original Platypus CleanStream(TM) gravity filter with less weight and improved durability. System includes two 4-liter reservoirs, 1 for dirty water and 1 for clean water; reservoirs have hang loops for easy in-camp use. To use, simply fill the dirty 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 others. Dirty 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 dirty reservoir to backflush the filter. Reservoirs feature SlimeGuard(TM) antimicrobial treatment for taste-free performance. Platypus GravityWorks(TM) water filter system is compatible with Platypus Bottles, Water Tanks(TM) and Big Zip SL(TM) reservoirs, all sold separately. - $89.93
