Review Summary
Casey and his friend try the Grayl GeoPress water filter bottle on water taken from the nastiest body of water they could find, some disgusting little pond of stagnant water in Florida. They show that the water is crystal clear and actually drink it, empirically demonstrating that this product can be safely used on really really dirty water in an emergency if no other source is available.
