  • This is the one to get
Size: 6L
I researched these life saving water filter straws for awhile before I decided to get this one. The reason I chose this one over the others was because there is known flaw in the filter straws. They work great the first few times and the the water flows through really good and then it goes down to a trickle drip to not working at all. This one particular one, has where you can suck through the straw and fix it, it gets rid of the air bubble trapped inside. The other ones don't have this feature. Also I watched some videos users uploaded when they used the blue bag and got the most swampy water you could get and they filtered it and the water come out clean. It really looks to be the best unit to purchase to have on hand incase tshtf. I have not used my unit, but it arrived clean and looks new and I feel better that I have at least something to get water if the power grid goes down. ... show more

  • Waiting for response from the company...
Size: 6L
UPDATE: I emailed the company about filter not working and they got right back to me. They asked a couple of questions and have mailed me a replacement filter. They were very responsive and easy to work with. My new filter is on its way. I will continue to update. I bought this last week. I tested it and worked great! I decided to use again this week just to be sure I have it all down and it has refused to work. The water would go through the hose so I removed the filter and it was not the bag or the hose. The filter itself is not allowing more than a drip through. I tried using it as a straw that did not work. I've taken it apart and can't see any obstructions. I have emailed the company and will update this review once it has been resolved. When it worked, it worked great! And the water tastes clean. ... show more

  • Air bubbles stop/slow the flow...
Size: 6L
So I've owned a few of these bag style water filters. All of them have ended up slowing to such a slow trickle it was unusable. I used this one on a trip to Dardenelles Lake in the Tahoe Basin (California Sierra Mtns) where the water is clear, cold and tasty. The first 4 liters flowed nicely. The first liter poured out like a tap. Then it slowed but still was decent. Then by the second bag (hard to fill to 6L, 4L is easy to fill and carry) the flow slowed to a trickle. By the third bag, it was fast drops. By the fourth bag, unusable. So I took it apart and used some of my precious clean water to try to clean/backflow it. The charcoal filter was covered in sediment/algae and the other end was also. So I cleaned it off, put it back together and it was a bit better but slowed to a trickle again by the end of 4L. I never did get it going fast again. Once again, like all other bag filters, dropped to a fast drop. About 20 min to fill a 1L bottle. Pretty pathetic. Returned home, backflowed it with tap water and let it dry. TRied it again with tap water and it was not working at all. A few drops per minute!!! I packed it up to return but I hesitated. Why would it slow like that when it's not even visibly clogged?!? I started to do some google research and started reading about air bubbles in filters slowing the flow. The nice thing about the Membrane Solutions filter is that the filter itself is a "straw" style filter that you can use directly to your mouth. So I used it like a straw and man, it was super hard to suck any water out of a cup. But I persisted and soon, I was able to get flow which got easier to suck out. I then put the bag back on and voila! flow was decent. So that's the solution folks, if this filter is relatively clean but slow, put it in "straw" mode, suck like crazy, get the air bubbles out, and your flow will return. Other bag styles don't have a straw mode so it would be harder to get air bubbles out. Now that I know what causes slow flow, I think I'm keeping this. Great bag filter in general. Good design. Easy to take apart and clean. Easy to put together. Easy to hang. They even sell filters separately (4 for $45) so i think I'll get extra to make sure I can keep one air bubble free and swap out as they all inevitably get air in the filter and slow to a crawl. But the solution is the suck the air bubbles out. Hope this helps someone else. ... show more
