A lightweight, reliable way of filtering and storing water in the field.
The supreme ease of the Autoflow Gravity Filter has converted many a backcountry traveler to pump-free water filtration. This year, we've not only improved the food-grade lining for better tasting water, but we've made the overall design far more compact so that the luxury of effortless filtration and storage comes with no bulky packing penalties.
In addition, we're offering a smaller 2.0L AutoFlow filter to provide backpacking duos a system sized optimally for two.
Gravity fed water filtration systems are quite new - the MSR's Autoflow Gravity Microfilter is very light indeed - so its ideal for camp use. On the downside filters can get clogged - and this one will be no different - if you expect to take water from sources without sediment then this would be a good choice to filter out the nasties. Heavily contaminated water will clog it quickly though and it would only work excruciatingly slowly!
This updated model now comes with a Dromlite Bag. MSR's DromLite Bags are made from durable material with a strong construction, this makes them a good option for longer trips.
