ABSTRACT:
A backpack containing a gravity flow water filtration system. The backpack incorporates a compartment at its top to hold a reservoir of untreated water, and a compartment at the bottom to hold a reservoir for filtered water. A tube and filter connect the two compartments, and a drinking tube and mouthpiece allow the user of the backpack to drink filtered water from the filtered water reservoir. In some embodiments, the bottom compartment is accessible from both ends, and can store other items as well.
