When you suck on your Survival Straw, water is forced through hollow fibres that remove the dirt & semi-permeable reverse osmosis membranes that remove salt from the water.
This straw is available in the nearest Bunnings Warehouse, Anaconda and on our website www.survivalstraw.com for $35.95. And remember drink freely
