    • Unreal this product is not more popular.
I purchased this item for use on long backpacking trips with minimal and sketchy water sources. I seriously think it can draw water out of a spoon. In ultra shallow and murky water sources I layed a bandana down as a pre-filter and was able to draw water in under a half an inch. Also the speed at which this collects water is unmatched by the accepted filters like the Sawyer Squeeze or Be Free by Katadyne. I Highly recommend this item. ... show more

    • Great filter
I picked this up as a lightweight alternative to my Katadyn Vario after a friend had one on a backpacking trip. Taste wise, the lack of carbon filter means that there are more flavors not filtered out. This isn't much of a problem where the water is fairly clean already, however if you in an area that the water tastes funny (or really dont like any taste) I would advise a larger filter like the Vario or MSR equivalent that has a carbon filter assembly. Speed is good - again, the streams were clear/fairly clean so we didn't run into any sediment buildup that may be an issue to flow. One thing I have yet to work out a good solution for was the pickup end is a lightweight strainer that tends to float with the intake up. In a fast moving stream, this tended to cause it to suck in air and not pump as efficiently as a fully submerged intake. Not the fastest, but will get you clean water reasonably well. I did test the backflush procedure before leaving, following the instructions it wasn't too hard but the new valves took some time to coax into action at first - once they were working it was really easy. Using it as my day trip filter with 1-2 people, and I can see it working well for light backpacking with 1 person very well. If you have more people in your group, the extra efficiency given by larger pumps likely will serve you better. The Vario was pumping 8-10L every morning and night for 5 days, this pump does well for 2-3L before the ergonomics start to work against you. All that said, its a great value and will be my main pump for everything but the larger trips. ... show more

    • This is a great pump filter
I have had 3 of these filters so far. I have a sawyer and a sawyer mini. I don’t like the sawyers because there are too many components including either the syringe to back flush it or the adapter for your smart water bottle to back flush it. I read a review that said this pump filter weighs about a pound and that isn’t true. Mine weighs about 8 oz. You can pump water from a very shallow poor quality water source, 3 liters per minute and it will fit right on a Nalgene bottle. You can push it into a smart water bottle but it doesn’t fit well. However if you use a short straw instead this thing can fill everyone’s bottles at camp in just a few minutes. A sawyer system will take 1/2 hour or more doing a squeeze method and hours doing drip filtration. Also this can be back flushed just by turning 2 valves around. You don’t have to carry anything extra. In defense of the sawyer it is 2 oz lighter and it’ll filter thousands of gallons while the hyper flow only does 100s of gallons. But guess what? I really doubt I’ll use more than a few hundred gallons backpacking during my life. ... show more

    • I've used mine for 10 years
I've had the hyperflow for ten years. It's solid. Most people just can't handle it. I don't have to backflush every 8 liters. And I do use the prefilter which is critical to good performance. Setting up the backflush is rather straightforward. I might backflush once a week on extended hikes. I honestly prefer this filter to the Grayl for extended back country. Freezing? I just put it in my sleeping bad and forget it. I do recommend this product to people who can handle. ... show more

    • fast and convenient water filter
this is an amazing filter!!! i've used a small sawyer hand filter, as well as a 2L gravity filter before, and this is by far the most easy and quick to use out of all my filters. remove the safety cap, throw the pre-filter into water and start pumping! about 10 pumps to fill my 750ml water bottle, takes about half a minute! comes with a nagaline/msr bottle/reservoir adapter, but i don't take that on the trail with me for short weekend trips (i only use it for the back flushing when i get home). if i carried a nagaline bottle with me, i would just replace the cap with this adapter for convenience. typically i'll just fill my water bottle without any adapter, cradling the bottle under my arm and pumping directly into the container (then i use the container to fill my zip top reservoir). have not yet tested if this can attach directly to a regular plastic water bottle, but i believe it is designed to do this. worst case you could cut 3-4"of the tubing and use that as a straw to fill any container (or your face :) ) directly. i read a lot of complaints about the back flush process, honestly after watching one youtube video i was able to easily back flush the system. it's not that hard, just make sure you aren't in a position to have one of the rubber flow pieces roll away. the only drawback is you do need that nagaline adapter to get the job done properly - that said the sawyer needed that big syringe thingy which is only marginally lighter. overall i definitely recommend this product, it's been a great addition to my backpacking kit. ... show more

    • Highly recommenced for solo and small group backpacking trips
So far so good! The filter is very easy to operate and has an excellent flow rate that is nearly as fast as my Katadyn Vario. It is extremely light and takes up little space in my backpack. The included water-bottle lid (quick attach) doesnt fit my water bladders or the majority of my water bottles, but i was easily able to attach a tube to the filter outlet to fill my water storage devices. The backwashing procedure is very simple and overall is much less maintenance than the Katadyn Vario (which has way too many seals and is a constant battle to fight leaks and water bypassing the seals). The entire process of disassembling the pump (unscrew to parts, and reverse 2 check-valves) is simple and takes a few seconds. My only complaint is that the filter needs to be backwashed more often than i would like ... show more
