The MSR AutoFlow Gravity Microfilter utilizes the same innovative Hollow Fiber technology found in MSR’s award-winning HyperFlow Microfilter, but offers it in a completely pump-free format. Perfect for family camping or base camp usage, the filter's reservoir can be filled with dirty water and suspended from a branch, allowing gravity to do the rest!
The ground-breaking Hollow Fiber Technology used by the AutoFlow Gravity Filter enables it to efficiently and effectively filter up to 1.75 liters of water per minute! The 0.2 Micron cartridge is completely field maintainable and long lasting, effectively filtering up to 1000 liters of water before needing replaced.
Rather than relying on the pumping required of most filters, the filter allows water to run from its collection "bag" through an output hose and the Hollow Fiber filter without any hands-on effort. A connection at the bottom of the output hose allows water to be filtered directly into the water container of your choosing.
NOTE: The AutoFlow Gravity Filter is effective against protozoa, bacteria and particulates. It is NOT effective against viruses.
The MSR AutoFlow Gravity Microfilter is available in 2L (weighs 10 ounces) and 4L (11.1 ounce) size options.
