This is something that everyone really should have in their hiking or bug out bag. For around $10-15, the Frontier Emergency Water Filter System Straw will filter 75 litres of water, remove pathogens and contaminants down to 2 microns in size including Giardia, Cryptosporidium and E.Coli, and the activated carbon filter helps reduce waterborne chemicals and improves water taste. You simply fill a cup or water bottle with water, and drink through the straw. Simple as that. The Frontier water filter straw weighs next to nothing, so you can easily pack one on even a short day walk – and even if you’ve got a larger filter pump that you carry, the Frontier water filter straw makes an excellent backup.
