The MSR Platypus GravityWorks 4L Water Filter is changing how people filter water. Delivering four liters of filtered water is just 2.5 minutes with no pumping, there’s simply no easier or faster way to get safe water away from home. 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. The MSR GravityWorks 4L Water Filter System includes two 4-liter reservoirs, 1 for dirty water and 1 for clean water plus the reservoirs have hang loops for easy in-camp use. The MSR GravityWorks 4L Dirty reservoir features a quick-disconnect valve that automatically shuts off the flow of water when the hose is disconnected. The GravityWorks reservoirs also feature a SlimeGuard antimicrobial treatment for taste-free performance. Ideal for bigger groups, the system’s eight-liter capacity eliminates both the worry and hassle of keeping plenty of water around for anything you need. The MSR GravityWorks 4L Water Filter delivers fast, pump-free performance with even less weight and more ease. Add one top your pack today.
