We do a family backpacking trip to a lake in Yosemite every year or two - and we can have more than 15 people there at a time. This means we have had to take turns pumping and sharing just 2 or 3 filters and it takes FOREVER. This sweet setup takes hardly any time... just scoop up some water and filter away. I think this would be helpful even with 2 people since it's super quick and then you'd be able to fill your water bottles and have water for cooking. It's also nice because you can store water in the clean water bag and refill as needed.LIMITATIONS: You definitely need something to hang them from (trees work great). You also need a source of water where you can scoop out a bucketful of non-nasty water. And be sure to read the directions about reversing flow just a little each time to un-jam it since particles build up more quickly than when you're pumping.Super easy and user friendly. I just wish we had gotten one sooner!!! ### ⭐⭐⭐⭐⭐ Where was this on my last trip! *by H***K on August 11, 2015* Used it for a 4 day backpacking trip in the High Sierras and it worked like a charm. Very easy to use and light weight. I wish the little pouch it came with was a little larger. Packing it back into the carrying pouch was a bit of a pain, but other than that it was a breeze to set up and use. We had 11 in our group and it took care of all our filtering needs. So simple to fill the dirty bag with water, hang it from a tree and let it filter water into the clean bag without having to pump and pump and pump. It is surprisingly quick as well. I think the system was the best camp gadget we had on the trip. Everyone loved it. Even the "proud" guys that were set up with techy filter systems of their own admired this setup. I have no need for any other filtration system after experiencing this. ### ⭐⭐⭐⭐⭐ Filtering Water Was Never So Easy *by G***S on April 27, 2015* This filter system works pretty darn good. I took it on a 3 night backpack trip on the Escalante River in Southern Utah with 6 people. We filtered between 30 and 40 liters for the trip.The filter started getting real slow by the last night and I was worried it was about done, for its useful life, which seemed pretty abysmal. Southern Utah typically has silty water, but the early spring runoff water we gathered appeared very clear, so I was quite surprised that it was going so slow with such little use. It even seemed to have stopped flowing. Tried back flushing while squeezing the clean water bag to increase the pressure going back through the filter. It helped, but not as much as I’d hoped. I always back flushed a little water as the instructions say to do, which I guess is mostly to get the air out of the filter so it will flow quicker. This is also supposed to clean the filter, but seems pretty pointless when you’re running the same water back through the filter again into the clean bag. When I got home I did a proper back flush, running a few liters of clean water back through the filter and discarding. This is really what is needed out on the trail as well. The first bit of water from the back flush was a little dirty, so even though the river water looked clear, there obviously was some bad stuff in it. After that back flush, the filter performed stellar again, taking 3 minutes to run 4 liters of clean tap water through it. Next time I’ll do a proper back flush on the trail when it starts slowing down, or back flushing a little onto the ground each time when filtering. It's easy to do.The conclusion: I love this filter system. I always hated pumping while trying to keep the intake hose out of the muck and sand, and getting very bored and worn in the process. There’s no waiting for dinner any more, and filtering while hiking is a quick process. I used to carry a ton of water, but we all only carried a one liter bottle, and stopped to refill if needed, which we did once during the day and called it a rest stop. The temperatures were cool, so in hotter weather it might be necessary to stop more than once, or carry a second bottle. In any case, I’ll never carry a gallon of water again, unless there is no water along the way, which does happen sometimes. We always check the maps for sources of water before heading out.Other reviewers have suggested or warned that you should carry a second filter system in case this one plugs up. I took a second filter cartridge, which is a lot lighter than a whole second filter system, but that shouldn't even be needed with proper back flushing. I didn't need to use that second filter.Filtering water is now a non-issue. The hardest part is walking from camp to the water and back again. It’s hard to complain much about that. ## Frequently Bought Together - Platypus GravityWorks Group Camping Water Filter System - Platypus Gravityworks Carbon Element - Platypus, GravityWorks Filter Cartridge --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.lk/products/639167807-gravityworks-4l-system](https://www.desertcart.lk/products/639167807-gravityworks-4l-system) --- *Product available on Desertcart Sri Lanka* *Store origin: LK* *Last updated: 2026-05-11*
