About this product

MSR Autoflow XL 10L Gravity Filter - This extra-large AutoFlow gravity filter system delivers 10 liters of clean water fast—all while you set up camp, prep dinner or relax.

And its big capacity means fewer trips to the river to haul the water you need.

Similar in packable size to a 4L system, the AutoFlow XL system's durable flat base doubles the water volume for only 340 g (12 oz) of total weight.

Ultralight and supremely packable, it offers the luxury of pump-free group filtration for basecamps, scout troops, horsepackers and other backcountry groups.

And just one 10-liter fill of the reservoir can supply 1-2 people with a whole day’s worth of clean water.

Features: Effective Against: Bacteria (99.9999%), protozoa (99.9%) and particulate.
