25 Days of Gear: MSR AutoFlow Gravity Filter


($120, cascadedesigns.com)

The AutoFlow microfilter from MSR is hands-down the best gravity water filter we’ve tested. And test we did, putting it through the wringer on a 25-day winter Grand Canyon trip where we asked it do all the filtering for a group of 16 boaters. The compact bag filter was still flowing hundreds of gallons later when we hit Lake Mead, continuing to keep the nasties out of our crew’s drinking water. The big innovation is that when the filter starts to clog, it can be attached to the bag backwards, which pushes all the gunk out of the filter element. When the water runs clear, flip it back around and it’s good to go. The AutoFlow has been around for a while but the latest version is even lighter bringing the total weight down to an impressive 11 ounces without compromising performance.
