GravityWorks Water Filter System

<p>The principle of Platypus' GravityWorks water filtration system is very simple: you fill dirty water into the top bag and as it passes down into the clean bag, it is cleaned by the hollow fibre filter. No pumping, no stirring, no chemicals - gravity does the job.</p><p>Each microfilter is individually tested and meets all EPA and NSF guidelines for the removal of 99.9999% bacteria and 99.9% protozoa. The filter can be cleaned in seconds after use and is immediately ready for work again. The whole system can be stored compactly and takes up little space in your backpack.</p><p>The dimensions given are for the 6-litre GravityWorks water filter system, the 4-litre system weighs 325 g. Both systems contain two 6 and 4-litre water bags, a replaceable hollow fibre microfilter, tubes, a clamp and a storage bag.</p>
