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 which 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. Please send links to more resources.

Litekamper review Aquapure Traveller

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. My plan is to fill another bottle from this one so I did a quick check of flow rate by simply filling from the kitchen tap - which is probably not as clean as Tasmanian wilderness rainwater and found that I transfer the contents to another bottle by squeezing in under 20 seconds which seems a pretty good flow rate.  I'll add more following the walk.

Aqua Safe Straw Aqua Safe Straw AquaSafeStraw is a high tech, tested and approved water purification system that removes 99.9999% of waterborne bacteria including Pseudomonas, Escherichia coli, Staphylococcus, and Fecal Coliforms, plus parasitic contamination by Cryptosporidium, and Giardia. 

Am not so sure this is a good idea from a contaminated source - but it is an option.

Outback Filter

Bota of Boulder Outback Filter

The Outback is a water filtration system that is easy to carry and use. Using innovative tecnology, the Outback allows the user to filter water from most U.S. streams, lakes or ponds. The filter removes 99.9% Giardia Lamblia and Cryptosporidium cysts.* The Outback filtration matrix is comprised of inert, synthetic polymers, molecular sieves and microspheres that have been specifically configured to trap and retain these organisms while inhibiting the growth of bacteria. This process, also known as tortuosity has little effect on the flow of water molecules, but presents a rugged, microscopic obstacle course for parasites. The result is safe water that is instantly available for drinking without prior disinfection all in an easy to use, lightweight Nalgene™ ATB bottle. This filter is designed to have very little back pressure and is easy to squeeze with a faster flow rate.
Chlorine tablets Aqua Pura chlorine tablets Any camping store will be able to sell you water purification tablets.  Simply follow the directions.  It is best to process your water as long as possible before drinking to reduce the bad taste.

Make sure you pick a tablet with the appropriate amount of chlorine for your water container.
