    The AutoFlow Gravity Microfilter represents the latest evolution of backcountry hydration, combining water filtration, storage and collection into a single, lightweight system. With the latest Hollow Fiber technology and the power of gravity, the AutoFlow is fast too—up to 1.75 liters per minute without a single pump stoke. 4-liter reservoirs allow you to filter large quantities at once making it perfect for groups, while quick and easy tool-free cleanings maintain high flow rates on extended expeditions.

    I have found this filter to be perfect for me. I like the fact that there is no pumping, makes it very convenient. If water is not close to where I am camping for the night I will fill my water bottles at the water source, and then refill reservoir on the filter so that I have water for the morning. Another noteworthy feature is the fact that it can be back washed, so the cartridge lasts much longer, and the flow does not diminish as quickly. The only downside is that it needs to be dried completely before it is stored for any length of time. I cannot see myself purchasing another pump filter after using this.

    I purchased the MSR Gravity Filter to replace a Pur-Hiker I have had for 15yrs, and I'm glad I did. No pumping! It is very fast, convenient, back flush-able on the trail, and it is light weight and compact too. I used it for about 6 weeks in the woods last year and just see no downside at all. It never gave me any trouble and performed wonderfully. Definitely recommended... Did I mention No Pumping! lol
