You'll be blown away by how fast you can fill a water bottle with the MSR HyperFlow™ water filter.

Backpacker April '08: ''The HyperFlow is so fast and light it converted several editors who had sworn off filters in favor of chemical treatment.''
Hollow fiber technology offers an extremely high flow rate of 2.75 liters per minute
At just 7.8 oz., the HyperFlow is the lightest, most compact pump filter created by MSR
Filter physically removes particles, protozoa, and bacteria down to 0.2 microns in size, including giardia, salmonella, cryptosporidia and others
Pump is fully field maintainable and does not require tools for complete disassembly
Included Quick-Connect™ bottle cap interfaces with MSR hydration products, Nalgene bottles and other containers with 63mm threaded openings
Quick-Connect™ cap allows the pump to attach directly to the bottle or hydration bladder for the most convenient filling
Included prefilter attaches to the end of the intake hose and blocks larger contaminants from entering the microfilter
Prefilter floats near the surface of the water to avoid intake of contaminants located at the floor of your water source
Over-molded end caps on the pump provide an excellent grip and pumping comfort
Adapt the HyperFlow pump into a pump-free gravity filter with the HyperFlow Gravity kit, sold separately

MSR has identified and fixed a flow rate issue affecting some cartridges in MSR HyperFlow microfilters. As of February 11, 2009, all filter cartridges sold by REI perform to flow specifications.

Please note: MSR products can only be shipped to U.S. addresses.

Made in USA.

Comments about MSR HyperFlow Water Filter:

I own several of these, and love the product. Some reviews talk about the pre-filter screen not staying down, I have not had this problem. The pre-filter screen has a velcro strap around it, we simply loosen the strap, and insert a small rock or stick to keep it in place. It is easy to prime, and lives up to the name of Hyper Flow. We have only used it in fairly clear, running water; and have never had a clog. As long as both of the valves are in the correct position/direction of flow, and the hose is not kinked, it is easy to pump. We usually fill either 4 liter or 6 liter dromedary bags, and usually two consecutively each time; they both are filled in a relatively short amount of time too. There is no plastic after taste (depending on the container you pump in to) or iodine taste that you get from other filters either. This way, we never run out of good tasting, clean cooking/drinking water in camp, or on the trail. We flush it with purified water or filtered tap water when we return home from our outings. Remember, there are two check valves that need to be turned to flush the filter. Also, take it very slow on the filter flush, you are basically forcing water through the filter "against the grain". Love this filter and flow rate! Happy camping!

Comments about MSR HyperFlow Water Filter:

The Hyperflow seemed great at first, the videos make it look so simple. I tried at home first to get it used, then this past weekend out hiking. The float does not stay upright so you have to reach in the water that you are trying to avoid touching, to flip it back. Connection to bottle is not great and leaks water like a spray. And if you watch the part about back filtering to clean it, it is very complicated. I love MSR products, but this filter is a bust.

Comments about MSR HyperFlow Water Filter:

I have used this filter for 3 nights out before it was unusable. I had purchased it because it could be backflushed. In order to backflush you just reverse the 2 check valves and pump clean water. Having reversed the valves I'm afraid I'd break it if I pressed any harder on the pump. The water I had been filtering looks clear, but it plugged up quickly. This is the worst filter I've had from a longevity standpoint. Over the last 20 or so years I think I've owned 5 other filters and used several more that weren't my own. I'll return it in the am.

Comments about MSR HyperFlow Water Filter:

So far, so good. I haven't died of water poisoning or anything. It's light, easy to use, and the water tastes good. The one possible con is that you really need a nalgene water bottle. This product would kinda suck without one.

Comments about MSR HyperFlow Water Filter:

Went out for a 100 hike and this filter basically shut down after the first day. It was like pumping concrete. I have never had a MSR product be such a let down. MSR should give everyone a gift certificate for a filter of their choice.

Comments about MSR HyperFlow Water Filter:

My husband and I bought this for our 200+mile hike of the John Muir Trail this summer. We liked the lightweight small filter, apparent ease of use and previous good experiences with MSR quality. We tested it at home, made sure we knew how to do maintenance etc as the manufacturer required. At first we told ourselves that the daily back flushing would not be a big deal. Well let me tell you it was a big deal. Also, the pre filter silt screen only works with one side down. Yeah. How many people never pump from moving water that takes the thing and spins it all around. Terrible design on MSR's part. Not that much slower than other filters really but the big deal breaker was that you literally have to disassemble the stupid thing into 4 small parts, reverse some valves, reassemble it, back flush he filter cartridge and then reassemble it back. A very annoying thing to have to do in the wilderness where everything is dusty, etc. and you have to do it after about 8 liters. The worst filter money can buy for anything longer than a day hike!!!

Comments about MSR HyperFlow Water Filter:

I've used a range of MSR and other brand water pumps but this one clearly outshines the pack.
My use, over the last 3 years, has been to purify water during numerous back country outings (some up to 10 days). The water I pump is clear and appears potable so the pump is used to avoid ruining a good trip. I do not have experience using this pump in silty or high organic content water. I perform regular maintenance and the pump and filter have held up surprising well.
Maintenance is a breeze, pump volume is the best I've run across. I bought a spare filter but there is no need to change the original out, though I"ve pumped between 75 and 100 liters so far.
Finally, the carry sack just blew out along a seam and the kind folks at MSR promptly sent me a new sack without charge.
My hiking buddy has one also and dittos my sentiments.
