MSR Hyperflow Microfilter Water Filter
Expedition Light & Expedition Rugged!
Light is Right in the mountains but you also need durable, this is what you get with MSR & their Hyperflow Microfilter. A very creative design that is as durable as it is lightweight. A great flow of water makes filling any water bottle a snap. Highly recommended. Also let me address another review which talked about the pad flipping over in rivers that are moving fast, it has a small learning curve as to how to place the pad, it's the sacrifice you make for such a lightweight design, if you position it a few times it floats just right & that gets easier with time, also there are Velcro straps that you can attach a small stone too & it is a creative way to solve that problem especially if you are trying to fill your container from a river of white water that's really moving fast. I found that the pump itself is faster than the Katadyn or PUR or even the General Ecology water filters that I have owned in the past. I love this filter but then again, that's what you expect from a company like MSR. Lightweight & durable!

Not worth it!
I bought this after reading many reviews and knowing that MSR makes great products (normally). I used it on two backpacking trips and returned it to buy a Katadyn instead. The lightweight filter pad kept flipping over in a stream (not a raging river, but a babbling brook) so I basically had to hold it in the water while someone else pumped. Then the pump started sticking after only a couple liters. The pump is also a little awkward to hold. At the time it didn't have the big mouth adapter, so that would be a welcome change, but having the water container right there is a pain. For the money, you can do MUCH better.

Fast and easy to use
I bought this pump to replace an old katadyn pump that i have used since 2001 and it has not disappointed. The pumping is smooth and can fill a few water bags in just a few minutes. I have used this pump on multiday small group trips and the others on the trip were surprised at how quickly it filtered water. Great product.

So far so good
I've has this filter for a little while now and I'm happy with it so far. It is small, lightweight, and is able to filter water relatively quickly. I like the wide mouth bottle adapter and was even able to use some of the tubing to create an adapter to back fill my water bladder while still in my pack.
