Platypus says:
An ultralight and versatile water filter that makes it easy to treat water for 2-4 people on backpacking, hiking, and backcountry trips, the pump-free GravityWorks 2.0L Complete Kit filters up to 1.5 liters a minute. Plus, it comes with a complete range of adapters, and a high-capacity collapsible bottle, for easy tailoring of the system to meet different needs on different trips.
Our Verdict
Gravity fed water filtration systems are quite new - this one is very light indeed - so its ideal for camp use. On the downside filters can get clogged - and this one will be no different - if you expect to take water from sources without sediment then this would be a good choice to filter out the nasties heavily contaminated water will clog it quickly though and it would only work excruciatingly slowly!
There are a couple of versions of the Gravityworks now, the original had two hanging reservoirs, this one has one to hang somewhere with the clean side reservoir being a bottle - this format is easier to use once its full of clean water. Both the dirty resrvoir and the bottle receptacle are 2.0L.
The kit also includes a universal bottle adaptor. If you prefer to use a rigid bottle for your drinking water then the adaptor allows you to filter straight into it rather than the platy bottle that comes with the kit.
