The Survival Straw is promised to rid your drinking water from 99.99 percent of harmful bacteria, chlorine, water soluble heavy metals, pesticides, arsenic, mercury, EDB, Giardia and some other nasty stuff. It is supposed to last for 5,000 gallons (approx. 19 cubic meters) of water. We reserve the right to be skeptical to this information until we have had a chance to test it. Ed. The Exstream Orinoco (B) will according to the sellers filter or kill bacteria and virii(!) like cholera, e.coli, and polio. Additionally, it is supposed to remove 99.99 percent of Cryptosporidium Giardia. The Orinoco should last for 100 liters until it needs a new filter cartridge
