The 9 Best Gravity Water Filter Kit

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 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.

SP160 Single Bladder Gravity System
To set up the SP160 gravity-based filter 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 (separate container required for clean water capture).

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, which enables you to effectively backwash and clean the MINI filter using a standard plastic water or soda bottle.

SP2160 Dual Bladder Gravity System
Similar in operation to the SP160, the SP2160 system includes a second “Clean Water” 1-gallon reservoir to hold your filtered water. Fill the dirty water bladder with water from any source, then connect the MINI and tubing between the dirty bag and clean bag. Hang the dirty bladder to allow gravity to help water to flow through the MINI to the second clean bladder below.

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, push-pull cap, and hose guide.

MINI Filter, Full Size Performance

The MINI water filter houses a cluster of micro-fibrous tubes that use similar technology found in medical dialysis. As water passes through the side walls of the tubes, harmful bacteria and protozoa are trapped on the outer walls, so you can be confident your water is safe to drink.

Rated to filter up to 100,000 gallons, the MINI’s filtering membranes are sturdy enough to withstand backwashing using the included syringe, restoring up to 98.5% of the filter’s flow rate. Sawyer individually tests each and every MINI three times to performance standards before packaging.
