Waterdrop Gravity Water Filter Straw, Camping Water Filter, 0.1 Micron

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.

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!

Product is really versatile , the flow rate was outstanding as I used this unit to keep 6 guys hydrated, outstanding product and highly recommend

I’ve taken this Waterdrop gravity filter backpacking in the woods multiple times, and the part that matters most to me has held up: it’s easy to use, reliable, and filters water to a point where I’m comfortable drinking it. Skipping the boil is a real quality-of-life win on trail — that alone makes it worth packing. The listing sells this as a gravity system with a 1.5-gallon bag, a 0.1-micron / 5-stage filter straw, and claimed life up to about 1,400 gallons. On paper that sounds like hang-it-and-forget-it camp water. In practice I haven’t used it that way. The bag doesn’t hold enough water for gravity filtration to feel worth setting up for how I actually hike, so I generally squeeze the water through manually instead. That still works — I just don’t get the hands-free gravity workflow the product is marketed around. Build-wise it seems durable enough. Nothing has failed on me, and I still expect a few more trips out of it before I replace it. Four stars instead of five because the gravity branding doesn’t match how I end up using it. Not lower, because as a backpacking filter it’s still easy, reliable, and it gets me drinkable water without boiling.

I bought this three years ago and have used it on two backpacking trips—most recently two weeks ago. Don’t have a lot of experience with hanging water filters but am very impressed with this. Likes: The volume of water it handles, speed of filtration, and filtration quality. I really like how the tubing quick-connects to the reservoir which helps when filling the bladder or when not using. Extremely convenient to fill this by dipping in the lake, rolling the top closed and hanging it from a tree. Would be just as easy to fill this from a steam or falls. Bag and tubing clean and dry well. The materials are quite durable and I have not noticed any breakdown in the 3 years since purchasing. Dislikes: The plastic bag/bottle thing is weird but handy if you like that kind of thing. There is a plastic clamp that is supposed to stop the flow of filtered water. This serves to only slow it down rather than stop the flow, which is why we disconnect the tubing from the bladder when we’re done filtering but still have pre-filtered water in the bag. Would definitely buy again.

This is a great water filtration system for camping. For those who are used to pumping to get clean water, this will be a pleasant revelation. For those who have used other gravity feed systems this will be an inexpensive and surprisingly quick alternative. I recently used this on a 4 day backpacking trip and love it. Here are a few highlights: 1. The feed back is lightweight, flexible, and fills to 1.5 gallons in one scoop of lake water. (BTW, don't fill it all the way to 1.5 gallons--it'll work better at about 1.25 gallons.) My friend is going to purchase the bag simply because it's so much easier and more efficient than the bag his (very expensive) system came with. 2. The filter has a bigger barrel than my Sawyer, and thus flows at about twice the speed. 3. The filter can be back flushed with the provided collapsible bottle--no need to bring along a syringe for back flushing. 4. The hanging system (also provided) is high quality and works great. Here's what I don't know: 1. My friend and I suffered no symptoms of waterborne illness, but the flow rate was so strong when we first started using the system that I was worried that it might not be filtering. What can I say? I guess I'm suspicious because it worked so well! The flow rate did decrease on the 4th day (after filtering about 11 gallons of water). But even the reduced rate was similar to my Sawyer filter. 2. The instructions didn't say anything about back flushing. I went ahead and back flushed when I got home, since every other filter I've used makes some provision for cleaning/flushing. I don't think it damaged it, but don't know for sure. I'd love someone from the company to respond to that question.

We bought this for a first time backpacking trip and it worked great!!!! Plenty of water flow and worked quickly. Our friend with a very expensive one agreed this one worked better and wanted one himself . Great purchase!

I just used this backpacking near Manistee River; we used it daily and we didn’t get sick. It was easy to use but I knocked it down 2 stars as it does not remove the taste of the tannins. I previously hiked this same location using a name brand pump style that was a pain to hand pump but produced good results and filtered the taste. If I didn’t have flavored electrolytes to add to the water, I don’t think I would be able to handle the taste longer than a day or so. If they make another brand with drip filter style that can filter out the tannin flavor, I would have gladly paid more. Avoid this model if the water source has tannins or other bad flavors in it.

Love this product. I recently bought it for my backcountry camping in Algonquin. Super easy to use, water comes out tasting just like water - no weird taste or chemical taste. I highly recommend. The only thing I wish it has was another bag to store the fresh clean water. Hard to only have the water come out as is instead of leave it to filter in a bag ready to drink. It comes with a little water bottle but it only attached to the filter. I ended up buying a water storage bag with a spout and it was perfect

Arrived as expected and in prestine state. Haven't tested the filter yet though

Very good product

Fair price the stuff at MEC and Sail is overpriced. filtered water great we both drank 6+ litres while on camping trip from lake we were on no one was sick or felt off at all make sure when u backflush it you blow out the water inside it I wouldn't put it away with filter media saturated in water for storage.

I only received the big blue bag and hose no filter and small bottle is delivered, very poor delivery...
