## 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 the 1-Gallon Gravity System (SP160) comes with one bag 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, Leptospirosis, and E.coli, and removing 99.9999% of all protozoa (such as Giardia and Cryptosporidium). The MINI also filters out 100% of microplastics (independent testing laboratory Hydration, LLC.; microbiological report S05-03). With threads on both sides, you can screw the push pull 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. Sawyer Products has offered the best, most technologically advanced solutions for protection against sun, bugs, water, and injuries – everything from first aid kits developed for wilderness to point-of-use water filters that filter contaminated water to levels cleaner than U. S. bottled water.

## 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.

### ⭐⭐⭐⭐⭐ Clean, Clear, Odourless Water
*by L***Y on 27 June 2025*

Very impressed and confident with this filter. We used it for a 3 day camp by a river and it provided clean, clear and odourless drinking water for us.

### ⭐⭐⭐⭐⭐ The Sawyer large filter bag.
*by G***C on 18 December 2023*

The large size for filtration. Great product.

### ⭐⭐⭐⭐⭐ Great product, easy to use!
*by J***Y on 22 May 2018*

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.
