## Description

A lightweight, robust solution for filtering large quantities of water, Sawyer's Gravity System with Dual-Threaded MINI filter is ideal for backpacking, backcountry camping, and emergency preparedness. Available in two models, the 1-Gallon Gravity System (SP160) comes with one bag and a MINI, while the 1-Gallon Dual Bladder Gravity System (SP2160) comes with two bags (one for dirty water, one for clean) and a MINI. The Sawyer dual-threaded MINI water filter weighs just 2 ounces, fits in the palm of your hand, and is rated to 0.1 micron absolute filtration — removing 99.99999% of all bacteria, such as salmonella, cholera, and E.coli, and removing 99.9999% of all protozoa (such as giardia and cryptosporidium). The MINI also filters out 100% of microplastics. With threads on both sides, you can screw the flip top cap onto the MINI for easy on/off functionality while filtering. Convenient and easily packable, this single- and dual-bag gravity system doesn’t require any pumping and is perfect for camping, hunting, fishing, scouting, disaster relief, and emergency preparedness kits, as well as on adventure travel excursions where potable tap and bottled water are not easily carried or safe to drink. The 1-gallon bladders feature a wide mouth cap that allows for fast and easy filling, as well as a convenient carry handle. To set up a gravity system, first fill the reservoir with water from any source (a lake, stream, pond, glacier, kitchen faucet, etc.). Hang the bag — from a tree, the back of your pack, or hold it up with your hand — and connect the MINI to the included hose and let gravity do its work. Water will flow through the MINI to produce fresh, clean water for drinking and cooking. The SP2160 Dual Bladder Gravity System includes a second "Clean Water" 1-gallon reservoir to hold your filtered water. The SP160 package includes a dual-threaded MINI water filter, 1-gallon bladder, cleaning plunger, and gravity hose with adapters. It also comes with Sawyer's Cleaning Coupling accessory. The SP2160 package includes a dual-threaded MINI water filter, dirty water bladder, clean water bladder, tube adapter with shutoff clamp, inline adapters, tube adapter, long tube, hanging strap with S-biner, cleaning plunger, cleaning coupling, flip top cap, and hose guide. Since 1984, Sawyer has used technological advancements to create products that keep you outdoors — from the backcountry to the backyard — including insect repellents for both skin and clothing, water filters for camping and emergencies, and sun protection.

Review: Great product, easy to use! - 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.
Review: worked great for my canoe trip - 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

## Questions & Answers

**Q: How long does it take to filter 1 gallon?**
A: I've never timed it, but I've set it up, walked away, and returned :15-20 min later, and it was finished. I think it's safe to say it will filter a gallon in :15 min. or less, probably closer to :05-:08.

**Q: I already have a Sawyer Squeeze (and a mini for that matter).  Do you sell the gallon bag and tubing in a separate kit?**
A: The One Gallon Bladder is available as a standalone unit (SP108).  The Inline Adapters (SP110) and any 1/4" inner diameter tubing will allow you to use your filter with this system.

**Q: Can you back fill with enough force to clear filter in the woods by pouring water from bottle?  I'm guessing using dirty water contaminates clean end?**
A: It comes with a syringe you fill with clean water to clear the filter. It works really well! I used it on trail for a week. I just didn’t like the bag itself.

**Q: Does this use the same mini filter as the "sawyer products mini water filtration system"?**
A: A similar MINI filter but this model has dual 28 mm threading on the top and bottom so the MINI filter can now be used with a push/pull cap on the drinking side.

### ⭐⭐⭐⭐⭐ Love the product, wish the opening was placed better designed.
*by S***. on July 10, 2018*

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!
