Let gravity do the work.
Collect, filter, and store your water in the backcountry with the quick and convenient MSR Autoflow Gravity Filter. This field-cleanable filter lets gravity do the work and cleans nearly two liters of water per minute. The four-liter reservoir holds enough wet stuff for your whole group, and the adapter end piece fits onto most standard water bottles and reservoirs. It's field cleanable, too, so you can remove all the bacteria, protozoa, and sediment that's been filtered out and have a filter that's good as new in minutes.
