MSR AutoFlow Gravity Filter

Product Highlights

The MSR AutoFlow Gravity Filter utilizes the same innovative Hollow Fiber technology used in the HyperFlow Microfilter, but offers it in a completely pump-free format. Perfect for family camping or base camp usage, the AutoFlow Gravity 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 1.5 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!

NOTE: The AutoFlow Gravity Filter is effective against Protozoa, Bacteria and particulates. It is NOT effective against viruses.

Rather than relying on the pumping required of most filters, the AutoFlow Gravity Filter allows water to run from its collection "bag" through an output hose and the Hollow Fiber filter with out 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.
