MSR Autoflow Gravity Filter Review:

I was in the market recently for a new water filter and debated for a long time on what to get.  I started out with the Hyperflow, but the initial production of it rendered some flaws.  So 3 replacements later, I decided to go with the autoflow and was very happy with my decision.  (As a side note, MSR recalled all of their hyperflows and fixed the problem)

What I really like about the autoflow is the convenience of it.  I can go down to the stream, take up 4-6 liters of water, carry it back up to camp and filter it till I run out.  If I don’t have 4-6 liters of water that needs to be filtered, I can just let it hang there until I do need some more filtered water.  Very convenient when your camp is 1/2 mile away from the water source.

I also like the fact that is weighs almost nothing, 10.5 ounces.  This is great because I don’t feel like I am carrying a big bulky water filter anymore.  The Autoflow packs down to a 7inch by 4 inch bag and has mesh on it to allow for drying.

The only down side I can see to it, if it is even that, is that you are recommended to backflush it every 8 liters.  You only have to backflush it a half a liter and if it pretty simple.  I really do give  it a 10 out of 10, because MSR has made a filter that is easy, light, and super conveniant.

Until the next product,
