New in 2008:
Fill it, hang it, forget about it. The CleanStream Gravity Filter is the Platypus answer to simple, effective and fast water filtration. This revolutionary Hollow Fiber media filters 4 liters of water in just 2.5 minutes without a single pump stroke. Simply fill up the Dirty 4L reservoir, connect it to the rest of the system via the handy quick-disconnect fitting and hang the whole system from a tree, your car, or anywhere. Then go and cook dinner, chat with friends, set up your tent or whatever. With no moving parts you get a quick, 4-second clean by simply reversing the height of the reservoirs and a full 8-liter capacity provides on-demand water for any group size. The system includes two 4-liter reservoirs (one for Dirty, unfiltered water, one to collect Clean Filtered water), Hollow-Fiber Filter Cartridge, hoses and all fittings.
