You can never be too prepared when you're backpacking, and one of the best Water Filters & Purification to bring with you is the MSR HyperFlow Microfilter. Bringing along a water filter ensures you always have access to safe, clean water, and with a pore size of 1.2 microns, you can be confident the MSR HyperFlow is filtering out as many protozoa as possible. Plus, it has a flow rate of 3 Liters per minute, so you can filter plenty of water quickly for yourself or your group. And, at only 7.4 ounces, it's light and small enough to fit easily into your pack.
Features of MSR HyperFlow Microfilter
Testing: 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.
High Flow Rate: Pumps more than 3 liters per minute or one liter every 20 strokes.
Ultralight: Just 7.8 oz. (221 g).
Ultra-small: Just 7x3.5 in. ( 17.8 x 8.3 cm) makes it easy to take along even when space is at a premium.
Field-Maintainable: Can be cleaned repeatedly for flow recovery without tools.
Super Convenient: Quick Connect bottle adapter lets you filter water directly into a variety of containers, including all MSR hydration products and other wide-mouth containers

Encountered a lot of negative reviews about the product prior to purchase. Checked with MSR and they indicated early filter production problems as the culprit. Filter worked great on a 6-day Grand Canyon trip and kept the 4 of us well hydrated. The water we pumped was largely silt-free. Brought along an MSR Sweetwater SiltStopper pre-filter just in case, but didn't need it. Fol... Read more

I am new to Backpacking. My wife and I are getting started and our spending philosophy has always been do your homework, spend what you need to, and get a good product the first time. MSR has designed the hyperflow to be a great fliter. The instructions out of the box require that you hook up 2 connections and start pumping. Admittingly, the dissambly and reverse flowing can be...

One of the worst parts about backpacking is filtering all the water, gallons and gallons of water it never ends. Well with this little baby that huge chore is almost made enjoyable. Almost ;)

My wife and I are new to backpacking. After much reading, we settled on the MSR Hyper flow water filter. This filter packs down small for a piece of gear. Its only about the size of a small bicycle air pump. I am amazed at how much water this filter pumps given its small size. It can pump a little over a liter per minute for 8 minutes before it needs to be back flowed, which is... Read more
I haven't had the chance to use my micro filter yet but I received it in good time, and it's exactly as it promised to be. I know msr is a fantastic brand so I'm not worried!

I've wanted one of these for a long time, and mine has performed perfectly! It pumps so fast and is so light/compact. The first time I took it out on the trail I pumped about 14 liters before back flushing it. And after having watched a short YouTube video, back flushing was VERY easy! My friends all want one now, after I gave them a chance to filter their water with it. The th... Read more
