Platypus GravityWorks 2.0L Complete Kit (2013)

While most water treatment systems require you to suck water or pump water, the Gravity Works system takes advantage of gravity to draw the water through the filter. The Complete Kit version featured here includes a pump-free filter, a 2 litre Dirty Reservoir, a 2 litre Platypus Bottle for the treated water, plus hoses and caps that allow the hoses to connect to a range of bottles from brands including MSR, Sigg, Kleen Kanteen, Nalgene and CamelBak. To use the system you simply fill the Dirty Reservoir with 2 litres of water, then suspend the bag from a tree or rock so the outflow pipe can transfer the water through the filter and into the Platy Bottle below. The flow rate of 1.5 litres per minute is slower than other pump filters, but you can leave this unit to work while you get on with pitching a tent. At just 270g the Platypus GravityWorks 2.0L Complete Kit lighter than pump filters and packs down neatly into the supplied zipped pouch, so it can easily be stored in a rucksack pocket. A great system for lightweight camping and backpacking.
