Provide easy, reliable, low effort water when out on the trail

This set has been the envy of every hiker we come across (who doesn’t have one already). There’s not really a need to get the 4L set, as this filters so quickly (just a couple minutes) that you pretty much have endless water if you’re near a water source, it’s no big deal to hang a second bag and run some more through. We were offering excess up to others that had hand pump type systems. Among my friends at least 3 of us have this now, we’ve had ours out repeatedly this summer on trips. Hose is long enough to hang at head height and still have the clean reservoir resting on the ground. My friend has the connection to fill his backpack reservoir directly (I just usually dump from the 2L clean bottle into mine), but if you’re into that keep an eye out for the adapter. Don’t forget to install the little black hose clamp so you can easily stop it if needed. Get this – you won’t regret it!

this was a great choice! Its so easy to use

I had held out for a while on purchasing a filter and did a lot of research, this was a great choice!

Where was this on my last trip!

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.

Smart, simple, effective, fast

Great system. Convenient, gravity fed, hands free filtration. Brought the whole system the first time- ended up not needing the accessories or the “clean bag”- just ran the hose into our bottles. Next trip we will leave all but the essentials at home and not struggle with the small (and slightly wimpy) storage sack….but this is not a big deal. Get this thing!

On a CDT section hike we brought this and a new Steripen. Halfway through the trip the Steripen bulb failed – but this thing kept chugging along. This filters water so quickly that you can fill up 4L and still be too tired to start hiking again. I used it in combination with their inline carbon filter. Water tasted great and no problems. Will only bring this one next time. All the parts are very well thought-out. Note you can’t let it freeze, though; I kept it next to my sleeping bag.

I’m Never Using a Pump Again!

This gravity filter is phenomenal! It is super easy to set up and pack away. If I had to be picky, I would say the only complaint is that the clean water bag is difficult to get dry after cleaning, but that is a very minor critique for this product. Being able to refill bottles and water storage on site, and do it quickly, means I don’t have to carry multiple liters of water while hiking, which takes several pounds off the load of my pack. This is definitely recommended.

Peace of mind, convenience, and economy on vacation or when disaster strikes!

I carry this in my suitcase, since we never know to the condition if the plumbing in the old buildings in the big cities. Saves buying, carrying, and disposing of water bottles no matter the hotel or BnB. My Platypus was especially appreciated when we were hit by Hurricanes Irma and Maria in the British Virgin Islands last September. Thank goodness I had it!

Works amazing!!! We bought this water filter for a backpacking trip with my husband and daughter and it worked perfectly! When we got to water sources, we just filled it up and hung it on a tree and filtered it directly into our Gatorade bottles. It worked while we rested and snacked! It was easy to clean out and packs relatively small. It works quickly and effectively. The water tasted great and I would really recommend this to anyone!

Great water filter

Great water filter!! a must have for any Backpacker, using gravity instead of a pump or crank makes much more since. There has been many times that by the time I get to where I’m going that I am too tired to want to pump water through a filter, this solves that problem. I just fill the “dirty water” bag, connect the filter with the “clean bag” and I am good to go, cant get easier than that, I love it!!!

Easy Filtered Water.

The easy way to get filtered drinking water. I also picked up 2 of the Sawyer mini water filters to use with the system. Sawyers because they are smaller . lighter and pack up in a smaller package. This lets me have one Sawyer for a spare along with the filter that came with the system.
