Why We Like The Autoflow XL10L Gravity Filter

The MSR Autoflow XL 10L Gravity Filter is a larger version of MSR's ever-so-convenient gravity filter, appropriately sized for large groups of backpackers and campers, or two backpackers for a full day without refilling down by the river. This filter lets gravity do all the work for us and cleans nearly two liters of water per minute. The adapter end piece fits onto most standard water bottles and reservoirs. It's field cleanable too, so you can remove all the bacteria, protozoa, and sediment that's been filtered out and have a filter that's good as new in minutes.

Perfect for thirsty groups

This is a wonderful filter to take with a group or when you anticipate needing a lot of water. It filters quickly. It’s easy to set up and use. I like being able to fill the bag and walk away as it fills our water bottles.

Very, very slow

I should have tested this filter before going on the trip, but our first night we hung the bag to get some water and it took us an hour to get it to start barely dripping out. We made sure there were no air bubbles, pushed water through on both sides to flush it, and to no avail. For the next 7 days we managed to get the fastest rate of about a liter every half hour. Luckily, I had a steriPen for a backup. Our water sources were spring fed creek and rivers here in Alaska so sediment was not the issue. Now that I'm back home I'm testing it in the kitchen and it barely works. Unfortunately this must be a faulty product, and it was my fault that I didn't test this before I left so I could have left it behind.

If doesn’t flow, loosen cap on Nalgene

If you screw the filter too tightly on the Nalgene, it won’t flow. Perfect for us! After we figured it out.

MSR does it again! Another fantastic water filter. HIGHLY RECOMMEND!

After using my consistently reliable MSR MiniWorks for about 20 years, I decided it was time to upgrade to the AutoFlow XL for our annual trip to the Boundary Waters Canoe Area Wilderness, in Minnesota on the Canadian border. With three of us to filter water for, I did not want to have to pump that much water by hand each day! I knew I could depend on MSR for a dependable water filter. The Autoflow XL was AWESOME. Scoop up 10 L dirty water and filter it into my collapsible 8 L wide-mouth collapsible canteen or 1 L Nalgene bottles. I love that it screws right onto my wide mouth bottles, and it's easy to shut-off while changing clean bottles. I'll still use my MiniWorks for solo trips, but AutoFlow XL worked fast and easy, with no pumping! The only downside was on the first day we used it, we accidentally left the hang strap attached to the tree when we packed up to leave our campsite the next morning, and didn't realize it until we made camp later that night in a different campsite. We managed to hang it up in a tree using paracord, but I'm hoping to find where to order a replacement strap. Bottom line: EXCELLENT FILTER, fast and easy to filter water, backflow to clear debris if clogged worked well, and it was simple to clean for long-term storage when I returned home. Thanks for another great product MSR!

Light, easy, great so far

So far, love this. It's simple and light. Love having a bank of water in camp and definitely loved not having to pump while chasing my 3-yo around camp. The only thing that was a little tricky was getting water from a super shallow stream into the bag w/ out another cup or something. Not a biggie though.

SOOOOOO SLOW out of the box

Shame on me for not testing this filter before I went backpacking. Luckily we had backup filters. I finally got the chance to try out my new Christmas present in July. The instructions make it sound like you just scoop water, connect the hoses and one minute later you have almost 2L of clean water. No prep, back flow, etc needed. Not the case! I did research online when I got back from my trip to see if I missed a step, nope. I'm now timing it to see how long it takes to get 1L of clean water. I think IV bags drip faster. 33 Minutes later my 1L Nalgene is full! Ugh. I've always thought MSR was a top outdoor brand but this is super disappointing. I've submitted a customer support ticket and hope they backup their product.

Best filter for the desert.

My favorite filter. Use it for marginal water sources in the desert for work (trails, wilderness stewardship) and for pleasure. Dependable, robust. With the back flow function, and a preliminary container to settle out with alum, this filter can handle the muddiest, most marginal water when you really need it deep in desert backcountry. (please keep making it!)

Love the larger dirty water

Love the larger dirty water bag over the previous version. Speed is also great for group backpacking.

Absolutely Perfect for group backpacking

I have gone on 2 backpack trips win groups of 2 and this has been perfect. Easy to use, and fills extremely fast. The adapter fits perfectly on Nalgene bottles and Gregory water reservoirs. I have osprey reservoir and they have an adapter you can buy for $5 to easily fill. Just remember to leave a slight opening for air to come out when you fill.
