Unscrew the wide mouth opening and fill the bag with water from any source — lake, stream, faucet, etc. — and connect the included tube between the bladder and the Mini. After filling, hang the reservoir with the MINI below it from a tree, the back of your pack, or simply hold it up with your hand. Water will flow through the MINI to produce fresh, clean water for drinking and cooking.

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.

We also include our Cleaning Coupling accessory, enabling you to backwash the MINI using a standard plastic water or soda bottle (with 28mm threading).

The MINI can be cleaned and reused almost indefinitely with no expensive cartridges to replace… ever. We recommend backwashing and sanitizing the filter after every outing for optimized use.

Ideal for outdoor recreation, hiking, camping, scouting, domestic and international travel, and emergency preparedness, the dual-threaded MINI gives you a number of ways to access clean water.

With threads on both sides, you can screw the push/pull cap onto the MINI for easy on/off functionality while filtering to control water flow.

For even more versatility, screw the filter onto most disposable water or soda bottles for drinking (or backwashing with the Cleaning Coupling), or attach it inline to tubing between your hydration pack and bite valve (sold separately).
