The Xstream Straw is a hollow-fiber filter straw with a two-foot drinking tube and a two-foot extension, so you can drink from a stream bank or boat without kneeling in the mud. It claims 99.9999% bacteria, 99.99% protozoa and 99.99% virus removal over a 250-gallon life, with no chemicals, batteries or moving parts. That virus claim puts it above most straw filters, which handle bacteria and protozoa but not viruses. It suits hikers, travelers and emergency-kit builders who want a light backup; it is not a gravity or pump system for filtering water for a group.

The Xstream Straw Water Purifier is a filter straw for drinking water while camping, hiking, traveling, and in emergencies. It purifies water without iodine, chlorine, or other chemicals. It has no moving parts and needs no batteries, and it filters up to 250 gallons of contaminated water.
The mouthpiece comes with a 24-inch straw, and an additional 24-inch extension straw brings the total to 48 inches. This length lets you drink from a stream bank, a lake, or over the side of a boat without lying on your stomach. The straw is lightweight and compact enough to fit in a jacket pocket or small pack.
It removes 99.9999% of bacteria such as E. coli, 99.99% of protozoa such as cryptosporidium and giardia, and 99.99% of viruses. It is for use with any non-salt water source.
