A camping water filter has to be easy to use, fast and 100% effective at eliminating pathogens. The MSR AutoFlow Gravity Microfilter excels at all three requirements, making it a great choice for backcountry adventures.
Convenience and ease of use are the hallmarks of this filter. Just fill the bag, hang in a tree and let gravity push the water through the hollow fiber filter at a rate of up to 1.75 liters per minute. 4-liter capacity is ideal for base camp and groups. It also features tool-free cleaning so you can maintain high flow rates in the field.
