Sawyer Products One-Gallon Gravity Water Filtration System

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.

Took this recently on a 6 day river trip in Utah. Worked just as I had hoped. I used it a little different than the standard method. I settled the silt in a 5 gal bucket of river water (using alum-there's YouTube videos how to do this), then used the tubing to make a siphon, with siphon running plugged the tubing into the filter which was screwed directly in to the bladder. That way the bladder stayed clean, filtered water. With filter and bladder sitting on the ground next to the bucket, took about an hour to fill the one gallon bladder. An extra 6 inches of tubing would have made this method a little less fussy, but it worked just fine. Product comes with a good assortment of fittings to make a lot of things possible. In the pictures, the green thing on the bucket is a homemade deal (made from a pill bottle) to keep the tubing from pinching at the edge of the bucket, with rubber band to keep it in place

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!

For the price this was a great purchase, as it was cheaper than a couple of the other Sawyer offers. The Sawyer squeeze is reliable, easy to use, easy to clean or flush, and should last years upon years with proper use and maintenance. It's the perfect size and weight to add to a bugout bag, camping kit, or hiking pack. While I absolutely love the Sawyer squeeze, the water bag is absolute trash. It's semi-rigid plastic and the cap is bulky. The cap being the biggest issue, as it must sit perpendicular to the bag. Meaning even if you fold the bag and flatten it, the cap will stick up 2-3 inches. Additionally, the bag is loud (it crinkles when used) and it's difficult to fill.

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.

It is very versatile and can be backwashed for extended use. The lifetime of the filter is 100k gallons. That will outlive me. I just wish the directions of use were better. I had to spend a hour online to really feel comfortable with the many configurations and safe use. I HIGHLY suggest this product.

This is a lifesaver. I took this on a pack trip in the Gila Wilderness and it provided clean drinking water for the four of us for a week. I filtered over 4 gallons a day and it flows faster than I thought it would. The filter is easy to clean by backflushing and it is so easy to use, just fill the bag, hang it on a tree and it just fills up your water bottles with no pumping. Best of all, no sick campers and the water tastes great!

The weight of this kit is negligible, but it doesn't pack down neatly into a backpack pocket. But it is just plastic so rolling it up and scrunching it into the pocket works. If you are getting water from a source that can pour into the opening of the bag, or if the water source is deep enough to submerge the entire bag, it works great. Otherwise if you find yourself trying to fill this from a shallow stream, good luck. The plastic is stiff enough that it doesn't expand as water fills the bag. You have to use another container to pour water into the bag to completely fill it. Once filled though, it works exactly as intended and without only one minor gotcha. The bag doesn't naturally hang such that all the water will drain out through the line to the filter. That means you have to hold it and tip it or figure out how to hang it and keep the bag tilted toward the filter tube.
