Sawyer Products One-Gallon Gravity Water Filtration System

Works great! I use it for making a cloudy Lava Lamp clear.

Used this for three days this past weekend, and overall I’m pretty happy with it. It was awesome and easy to fill when I was access to fast moving water, but slow moving water forced me to try and either submerge it or sort of use a scooping motion to get it even halfway filled. There HAS to be a better place for the inlet on a bag like this.The filtering itself was plenty fast for me (a good excuse to drop pack for ten minutes) and the water tasted great. It was nice to fill up at camp and know you had water on tap for cooking, cleaning, drinking, whatever.I took a pic of how I rigged it up most of the time. I would loop the leash of my pole through it and back onto the pole to hold it, then attach the other poles leash and lean them against something with a wide stance, made it super quick and easy.Much better than pumping and is pretty light. Definitely happy with it overall!

Great product, easy to use. Just finished a 23 mile through hike on the Pine Mountain Trail, GA. Filtered the water perfectly, 1gal took less than five minutes, taste was perfect. Between the four of us, no one ever got sick or felt sick from drinking the purified water, no other treatment was needed. After the water bottles were filled each night at camp, we would fill it up for cooking water and cleaning dishes. Kept it hung on a 550 cord clothes line we setup and had no issues with the handle or the bag the entire time. If you are looking for a system for more than two people that is effective and easy to use then this is the right fit for you.

I have always used the Katadyn pump filters, but I decided to go with a gravity system to save some time and energy at camp. This was perfect, and for a great price! In one minute and ten seconds I was able to filter a liter of water, so it would only take about 5 minutes to filter a full gallon.The only downside is trying to fill the reservoir from shallow or standing water. This is where pump filters have the advantage, since all you have to do is throw in the line and start pumping. However, when you consider the low cost and weight savings, this is by far the better choice. I carried a cheap plastic water bottle I purchased from a gas station just before the trip, and filled up that bottle with dirty water and bailed it into the Sawyer reservoir. This worked extremely well, and then I just collapsed the empty bottle and stuffed it into the lid of my pack. Even if you can't find a place to hang the system, it's very easy to screw the filter directly onto the bag and squeeze clean water into a drink bottle or bladder system.Save yourself some money, some ounces, and time by ditching the pump and let gravity do the work! I love my Katadyn, but I think it will collect dust for a long time since the Sawyer has a place in my pack now.Update 7/27/18: I just used this filter on a 3 night trip for a total of six people. We used the filter at least 3 times per day. During the 2nd day of use the filter slowed down considerably, but it was still easier than pumping. I would suggest back flushing the filter after every gallon when filtering for larger groups.Also, we used the sea to summit lightweight bucket to get water from a nearby lake, then dumped the water into the Sawyer bladder. This system worked great because we didn't have to move the gravity filter and the water was easier to retrieve using the bucket.

Works well

WORKS

Love this thing. No issues yet really. I agree with other reviewers that the inlet on the scooping bag could be better placed, but honestly that is such a small complaint. The flowrate on this is excellent and I can filter into either a platypus (attachment included), or into 3 nalgenes. Perfect for group camping/canoeing, but i would use it solo too since it packs down pretty small and i love the convenience of a single bag being enough for filtering enough for a mountain house dinner, tea, a nalgene of drinking water, and coffee/oatmeal in the morning. It makes me wonder why it took me so long to switch away from my MSR Miniworks which is slow and you have to pump like a caveman! I backflush once a trip which is a breeze. I will bring the syringe if im going with a group or if the water source is dirty. This is another one that I would definitely replace if i lost it.

The Sawyer One-Gallon Gravity Water Filter works as designed. No instructions on how to use and assemble the filter were included with the filter when it was sent. The instructions had to be found online in a pdf document.
