Filtering up to 1.75 liters a minute without any pumping, the high-capacity Platypus GravityWorks 4-liter water filter system is an easy, fast way to get filtered water in the backcountry.
- 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; no pumping required
- 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
- Microfilter lifetime of up to 1,500 liters
- 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 (not included)
