Product Description

The MSR AutoFlow Gravity Microfilter is a lightweight water filter for safe drinking water in the backcountry. Whether you're on your own or in a small group, this makes filtering water simple. Just fill up the dirty reservoir from the source, hook up the hollow fiber filter and appropriate hoses and place the clean bottle on the ground below. You and your friend(s) can go about setting up the rest of camp and when you return, voila! Clean water to drink. Packs up nice once it's off to the next camp.

FEATURES of the MSR AutoFlow Gravity Microfilter

  • New reservoir made of durable film and an updated closure system reduce bulk for discreet packing
  • Improved food-grade lining ensures better tasting water
  • Uses the power of gravity to filter 1.75 liters per minute, offering the efficiency to multi-task at camp
  • Combines water collection, storage and filtration into one compact system
  • Can be cleaned easily and repeatedly for flow recovery

Rated 4 out of 5 by from quick water easy to use rapid flow Iam very pleased with how it performed .So nice after a hard day of backpacking to just collect water and let gravity do the work

Rated 4 out of 5 by from A luxury item After using a few pump-type filters this water filter is a nice upgrade. Speed is good with clean filter but becomes slow quickly without a cleaning every 2 gallons or so. This is the first filter that I haven’t broke, and that hasn’t caused headaches. Keeper

Rated 5 out of 5 by from Ease of use! I purchased the 2.0L to replace an older filter I had been using and am extremely happy that I did. Took it down to the bottom of Mee Canyon where water is relatively scarce and wound up filing it from a silt and sand filled source. The filter never really lost filter pace despite the contents of the water. No one in the group got sick and we were able to fill all of our personal containers and cook sets in no time. After getting out of the canyon, cleaning was a breeze with the backflush feature. Highly recommended as this removed all the sediment we had collected on the trip.

Rated 5 out of 5 by from This is the filter you need Bought this for our backpacking trip. Easy to fill and easy to use. Well designed product by people who understand what is needed on the trail.

Rated 5 out of 5 by from Too easy Who likes squatting over a stream while holding a bottle between your feet and pumping a little plastic handle for days? Not me. Who likes doing nothing and getting something? I like that.

Rated 5 out of 5 by from Force Multiplier Simply fill the bag and let gravity do all the work. It's the first thing I unpack when I find my campsite for the night. By the time I'm done setting up the camp I have 4L of fresh filtered water waiting for me.

Rated 5 out of 5 by from Filters Fast & Easy Purchased this to replace Katadyn & MSR pump filters used on a 7 day Canadian fly-in fishing trip for 6 guys. We filtered about 8 Liters per day and it filtered fast and easy as advertised. Much better than hand pumps. This is the way to go. However, because the water at the fishing lodge was so clean and clear I did not back flush except about 1 cup on the 4th day. On the 7th day it began to slow to half normal speed. I tried to back flush, but onlya half cup before it stopped. Would not filter in normal flow or back flush. I'm drying it out now in hope that I can back flush the clog and still use the cartridge. Still give it 5 stars because it worked great until I did not follow proper maintenance.

Rated 5 out of 5 by from Iiiit’s Great! This is a great lightweight filter that allows me to use all that water that I used to flush down the toilet. NOW! All that toilet water that we used to just waste is tasty drinking water. Turns the darkest soiled water into yummy refreshing drinking water. The Culligan man ain’t gunna make that happen. Buy it!!

Exactly what does it filter out and to what size particulate

Asked by: Dave
Hiya Dave, thanks for your question! This filter meets NSF protocol P231 for removal of bacteria (99.9999%) and protozoa (99.9%) from beginning to end of filter life in “worst-case” water. Hope this helps!

So instead of buying a Water Filter, I should buy a Water Pruifier, correct?

Asked by: tick151
Hey again! Correct, you will need a purifier over a filter to handle viruses in addition to bacteria. I'll leave you a few links to some MSR purifiers down below, I hope this helps! MSR MiniWorks EX Purifier System - https://bit.ly/2Wv8Bjr MSR Guardian Purifier Pump - https://bit.ly/2YXFbIA

Good afternoon,, Does the filter have a micron size that it filters down to? and, if we clean the filter as needed,, how many gallons will the filter last before we have to buy a new one.? Thank you, Russ

Asked by: Russ
Thanks for the question! The Gravity Microfilter physically removes particles, protozoa, and bacteria down to 0.2 microns in size. The filter has a cartridge life of 1500 liters. Hope this information helps!

Does this Filter Eliminate Viruses?

Asked by: tick151
Hello tick151, good question! Let me answer your question with an excerpt straight from the folks over at MSR..."For a microfilter, meeting the EPA Guide Standard means removing 99.9% of protozoa and removing 99.9999% of bacteria in all required water types." Unfortunately, viruses are typically 100 times smaller than bacteria and require a purifier to be handled. I hope this helps!
