Sawyer Mini 1-Gallon (3.78 L) Gravity Filtration System

A lightweight, robust solution for filtering large quantities of water in as little as 7 minutes, Sawyer’s 1-Gallon Gravity System paired with the included dual-threaded MINI filter is ideal for backpacking, backcountry camping, and emergency preparedness. 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.


  • 0.1 Micron Absolute Filtration
    • Removes 99.99999% of all bacteria, such as salmonella, cholera and E.coli, and removes 99.9999% of all protozoa (such as giardia and cryptosporidium). Tiny ‘U’ shaped hollow fiber micro-tubes that trap contaminants while allowing decontaminated water to freely pass through at a high flow rate
  • Dual-threaded Mini Filter
    • Impossible for harmful bacteria (like salmonella), protozoa, or cysts like E. coli, Giardia, Vibrio cholera, and Salmonella typhi to pass through the filter.
  • Exceeds US Environmental Protection Agency (EPA) recommended removal rates
  • Gravity Does the Work
    • 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.
  • 100,000 Gallons (378,541 Litres)
