Thanks to the three-stage filtration system it not only removes most bacteria and protozoa, it also removes viruses and many other contaminants like chlorine and heavy metals with the use of an integrated carbon filter. This is a feature that almost none of personal water filters have.
The filtration system isn’t driven by gravity or any electronics instead you need to manually pump to get the water filtrated. This can be very time consuming and tiresome if you need to filter large amounts of water.
The unique bladder filtration system has a total capacity of 8 liters – 4 liters of clean and 4 liters of dirty water. In a combination with the fast filtration process it provides enough water for a campsite without the need of constantly running after new supplies of water to filter.
