First few days seemed great. Filtered pretty quickly. But in the first week of a two-week canoe trip, the bag’s seam ripped (and duct tape wouldn’t hold water in). The only thing that saved us was that we had a backup option. Very disappointing

My husband & I do a lot of camping or hiking or just being outside & this works great! I had a backpack one but sucking the water out of it was a task lol. This one flows easily & it doesn't leak when turned to off.

I dont know well it filtered. I do know unless you love the taste of water out of a garden hose do not buy this. The garden hose taste was so strong even after I ran several gallons of water thru the filter that I tossed it into the trash

I bought this for a camping trip to replace another more expensive gravity system that I had used for years. The short version is; I was able to successfully use it, and I didn't get sick from it (which is always a plus) but some things could definitelybe improved. Read on if you want the full details.Pros-It's a decent price, and the one I got came with 2 filter straws and drinking bags as well.It definitely works, it filters pretty quickly (honestly a little too quick it seems, but we will get there in a second), and it isn't difficult to set up and use.The reverse flushing system is easy to use since the mouth piece can be removed and a bottle (or included bag) can be screwed into it.- If you are short on cash and just need something to filter some decently clean running water, then you could certainly do a lot worse.Cons-Unlike the systems I'm used to (which, granted, cost at least twice this) there is no degree of filtering done in the bag at all, everything just feeds down into the hose that connects to what essentially boils down to a lifestraw.So there is only that one stage of filtration, and that stage doesn't filter out everything, so I would still boil it unless you are drinking from a fairly pristine spring or running creek.Since there is only that one stage, it is really important that no leafs or debris is picked up when filling the bag, or the system will get clogged quickly. This could easily be remedied with a even just a screen in the bottom of the bag, but would still slow the process. I was only there for a night using this, and it was already noticeably slowing down and needed to be back-washed (which is necessary anyway with any of these systems, but really important here).The mechanism to stop and start the flow is cheaply made plastic and kind of difficult to use one handed. Not sure how long it would hold up either, since there was some noticeable whitening on the hinge part after one night's very occasional use.My biggest gripe is lack of compatibility with any other filters, and them not selling an upgrade that fits this system. (As far as I can tell, anyway)All in all, it's serviceable in a pinch, and it's worth the price. I wouldn't rely on this as your primary water filter in a true bug out situation though. Durability is definitely in question here, but I'll try to update after more uses. It's decent, but it could be a lot better. If you have the money then I would go ahead and just invest in a Sawyer, or higher dollar one. If you are strapped for cash, and just need something to work for the time being or an emergency, then it should work well enough for you, as long as you are careful about water sources and keeping it clean. Hope this helps someone out there 👌

I’ve used this a few times now and it’s been great. It’s lightweight so blanking it backpacking isn’t an issue. It has 2 filters in case of an issue. The flow is decently fast. The water I tried from a mountain stream had little taste. Overall, it’s a quality filter that I take on all my thru hikes.

It worked, but barely. Used very clean water from an alpine lake, and the flow started off ok but then became just a trickle. The filter is also designed such that you can’t just leave the bag attached and let it do its thing, you have to stand there and hold the bag to the filters mouth piece, which defeats the purpose of gravity fed, in my opinion.Ended up working for us for a one night trip, but it would have been extremely annoying if we were going any longer. I’d check out other brands of gravity filters.

Get for backpacking with Scouts. It took about 10 minutes to filter about 6 liters or 6 Nalgene Bottles. I would recommend a ball valve to screw the filter on, it would make it simpler to attach the filter while there is water in the dirty bag.

I don't know if that could be just me because it takes me back 60 years when I was a little kid and drank from hose that hung wrapped up on the outdoor faucet because the vinyl taste is there. Will that go away?

We used this bag and filter every day for a week of wilderness camping. I bought a second after being so pleased with this one. Flow rate is superb compared to competitor products. We had one or two days where an algae bloom heavily covered the surface water of the lake. We filtered water all week without problem. Backflushed easily on day 5 with clean water and was amazed to see the amount of algae and dirt that came from the back wash. Restored back to original flow rate. The bag is durable but I could see it getting damaged if not protected or stored properly. The water tasted good for the price point. Compact space saving design.

Was good for some time but after my fourth time camping using this, the bag started to leak water and doesnt seem to last that long

Came home from Uzbekistan with the worst case of what my grandma used to call the “gogo-amago” ever. Figured it either came from carelessly rinsing iur toothbrush in tap water, or eating a fresh fruit washed in tap water.Made an advance plan for our next trip to a third world country. No salads. No fruit unless we washed it ourselves. No smoothies unless they used bottled water. Don’t use room water provided unless we saw them filter it ourselves. Have a plan in place to provide so we won’t dehydrate and for tooth brush.This little gizmo is AMAZING. It is lightweight, super easy to pack, easy to use once you get the hang of it, cheap to use, and saves tons of plastic.My only fear is, the straw part is very sturdy, and so far the bag part is, too, but it seems much more likely to wear out, crack, or get punctured (even though it’s a thick plastic) than the straw. I wish they’d include and extra bag or two, as well as instructions to clean and store straw and bag.Well worth what seems to be an initial “investment”. Other travelers were jealous, and asked for details.Will be packing it for our next trip, to rural Morocco. Wouldn’t dream of traveling without it now. Has earned a spot in our minimal packing.Os: bought extra straws, but it seems like these things last forever. Hope we’ll get to travel enough to use the extras!

Very good alternative to the bigger brands. The gravity flow works well. The filter slowed down considerably after a few gallons, but was re-useable after flushing. Well designed water bag.

I am very impressed with this item for its ease of use and cost. The bag holds plenty of water for a whole day, so far no tears or leaks. The bag material is ultra durable, though the attachment mechanism and clamp for the straw could be improved, overall great product. The filtered water has a very neutral taste, but overall a great buy! 10/10.

It all folds up into a very packable size and filters over a gallon of water with surprising speed. The clamp on the hose dribbles a little bit, but that's just for temporary use so it's not meaningful enough to deduct a star. The outflow fitting on the bag does not leak. The water is not tainted with any plastic taste and it all assembles quickly. The bag does not leak when transporting full of water prior to use. Again, it filters very quickly with just gravity flow. It is a good price and I have no real criticisms.

It’s hard for me to rate this product. I have it stashed away for my bug out bag so I have not used but it looks to be a great product. Hopefully it works well if and when needed.

This filter is awesome, used it on a three day backpacking trip recently. No issues whatsoever. For everyone’s information however, the reservoir bag does not seal fully when filled. The top, although it folds nicely into a handle for carrying - which is amazing and super convenient - it does not prevent water from coming out the top if you, let’s say, put the bag down on the ground to get the straps adjusted or something. So the reservoir is not for carrying water for long distances, unless you’re prepared to always keep it upright and never put it down until you can hang it. Still super doable if you’re going short distances, it doesn’t spill when you’re holding it by the handle, just if you put it down on the ground while filled and it falls over.Other than that, this kit is awesome. Gives you the option of reversing the steps, instead of filtering the water into the small plastic water bottle pouch, you fill the plastic bag with the unfiltered water, screw the filter straw onto the pouch, and drink it directly out of the filter (basically a life straw). I think the bag might be half a liter that it comes with, so if you want a bigger pouch then you’ll have to order one. This is the way I’ve seen most through hikers using it, usually with the sawyer filter setup. But this filter gives you both options, filter the clean water from the reservoir into the plastic flexi pouch or any other bottles you want, or collect the unfiltered water into the flexi pouch, attach the filter directly to the pouch, and drink through the filter.Super lightweight, condenses into a really small volume, durable (I carried water in the reservoir for more than 5 miles, by hand, leaning it against a tree when I had to put it down, and the material held up). We used it for three days and that was more than two weeks ago, long enough for any water born sicknesses to have shown if it didn’t work. Great purchase.

Absolutely Exceeded Expectations!I took this on a 2-night hike in the woods with a Trail Life troop — 8 adults and 11 kids — and this water filter performed beyond what I imagined. It provided clean, fresh water for everyone, and we even had extra water left over. It was reliable, easy to use, and incredibly effective. No complaints at all — we all loved it. Highly recommend for any group camping or hiking trip!Will be buying a second one

I think this will be useful to filter out micro plastics and pollutants in my house hold taps!

Good quality and very good deal

Recently went to Boundary Waters for a week. Easy to use. Great water.

Fast and efficient, this blew all the others filters outta the water when we got to camp and started filtering water! Worth the money!

Worked great. Easy to use.

Works as advertised and looks great while doing it!

I have been trying to get an emergency prep started and thought this might be useful. I haven't used it yet but it's good to know it's there if I need it. It seems to be good quality. Reviews were pretty good that I did read.

I haven't used it yet, but I think its just what I wanted.

Great package for survival

Worke great

Great system to have in your bugout gear. Water in necessary for survival and this will get you by.

Product just as advertised!
