Manufacturer's Description

Introducing the most advanced personal hydration system available. Use the Expedition with clean or dirty water...its unique non-clogging forward osmosis filter provides you with unprecedented options. Use nearly any water source to generate clear drink. Purity levels are comparable to reverse osmosis systems, and the filter meets EPA standards for the removal of biological pathogens (viruses, bacteria, cysts).

How It Works:

The Expedition uses a process called forward osmosis, providing clean drink without the difficult sucking or pumping typical of in-line filters, and without the use of harsh chemicals.

The dual-chambered reservoir can be filled either with clean water through its round port, or quickly filled with dirty water through the wide roll-top opening for filtration. Just dip and go. Very little effort or time is required of the user. And because there is no hydraulic pressure involved, the Expedition will never clog, unlike every other filter technology.

The osmotic filtration is driven by a sports drink syrup, generating a diluted sports drink for enhanced hydration and performance. One small syrup pouch will filter an entire bladder of water, generating 25 times its volume in clean drink at the rate of one liter every hour and greatly reducing the amount of water you must carry in remote areas.
