Membrane Solutions 6L Gravity Water Filter Pro for Camping | NSF/ANSI 42, 372 & 401 certified; 0.1-micron 4-stage filter reduces chlorine, sediment, and odor for outdoor water

While I've not actually been able to test the flow rate of this filter in a gravity configuration, it works exceptionally well with smart water bottles. It filters the water well to make it more clear, it tastes good, and I've not gotten sick even though I've had some very mild immune responses; like one may experience after some vaccinations. From what I understand, this is just my body responding to trace amounts of bacteria which may still get into my clean water from cross contaminating it with dirty hands, and results in resistances to local bacteria. Not unlike how seasonal allergies may be less likely to significantly affect local populations who grew up with those allergens. The instructions are clear and easy to follow, but this whole setup is so intuitive I didn't need them anyway. I like how compact this kit is, rolling up nicely in it's bag, and the wide mouth of the flexible collection bag is very useful for scooping water out of places where a bottle cannot reach it. The system does not seem to leak, and I feel safe drinking the water it filters from running sources. But I still prefer to purify the filtered water I collect from standing sources with some Aquatabs, just in case of pet waste on the trails, or dirty shoes walking through the mud.

I've taken this on several long kayak trips and it has worked perfectly!

I bought this as a gift for my son that loves hiking and camping. He has enjoyed this product very much. He has carried it on many hikes and camping trips. Uses it for fresh drinking water and if cooking something over a campfire. I would recommend this product and I would purchase again.

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.

I've been going to the BWCA for 40+ years and have used various filters, capsules and other means to filter water and this is by far the most convenient and easiest filter I've ever used. Packs small and is fairly lightweight, has good water flowage and is easy and quick to fill. Great product!

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.

I will have to update since I am giving this to my son-in-law. Don't know when he will use it, but everything was included in the package. And not heavy to tote around on a hike when empty, either.

This came neatly packaged & seems to be made of quality materials. Haven't used yet but I'm confident I will be happy with my purchase.

Took this backcountry camping for a 3 day trip! It was perfect. It did the job!

Es ist alles in Ordnung, angekommen. Über den Qualität kann mich nicht äußern, noch nicht ausprobiert

Not used , but quality seems great, seems great value for the money, and good for everyone to have something like this at hand, in the car, home, go bag for unexpected disasters. Will purchase more for different place I might be in an emergency.

Estupendo como kit de emergencia
