Portable water purifiers for hikers. Note *Capacity of any device will vary depending on characteristics and concentrations of contaminants and inlet water pressure.
Below see a list of purifier devices that are available. Another option that will kill harmful bugs is simply boiling the water. Of course, boiling does nothing to reduce particulate matter so brown water boiled is still brown water.

|Aquapure Traveller||Specifications from web site:|
BPA free (no chemicals)
Bottle capacity 650mL (including when the filter is inside)
I got this bottle to provide my water filtration needs on a six day walk on the Overland Track in Tasmania Easter 2012. Here are my initial impressions. The Aquapure Traveller water bottle is made of plastic. It stands about 224mm high and the base has a diameter of about 90mm. At its widest point it is around 90mm across because of the offset nature of the top section. It fits easily into the side pockets of my various packs. The filter is built into the screw cap/mouth piece. On my scales it weighs 107 g empty and 750 g full – which equates to a water volume of around 650 ml.
