The Australian SureAquaStraw+ uses a membrane to filter contaminants to 10 nanometers (0.01 microns). This includes waterborne bacteria, viruses including Pseudomonas, Escherichia coli, Staphylococcus and Fecal Coliforms, plus parasitic contamination by Cryptosporidium, and Giardia. It’s a simple straw design that allows you to dip right into a water source and drink directly from it. Additionally, it is designed to filter up to 1000 liters(264 gallons).
