The minimalist, ultralight, and ultracompact GravityWorks 2.0L Bottle Kit uses a simple and easy design to connect the pump-free water filter directly to a water bottle or hydration reservoir, conveniently filtering up to 1.5 liters of water a minute for 1-2 people.

Collecting water is easy - simply open the top, scoop water, and close it up, while controlling the delivery of filtered water with the hose shutoff clamp. Just fill the dirty reservoir, hang it, and let gravity do the hard work - filtering water can be as easy as fill, hang, and relax.
