A lightweight, robust solution for filtering large quantities of water in as little as 7 minutes, Sawyer’s 1-Gallon Gravity System with 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.
Our lightest and most versatile personal water filtration system, the Sawyer MINI 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).
Weighing just 4.5 ounces, the 1-gallon bladder features a wide mouth cap that allows for fast filling and a convenient carry handle
0.1 Micron Absolute Filtration
Our water filters contain a high number of tiny ‘U’ shaped hollow fiber micro-tubes that trap contaminants while allowing decontaminated water to freely pass through at a high flow rate — eliminating the need to store water and reducing the possibility of water contamination after the filtration process.
The dual-threaded MINI is certified for 0.1 micron filtration, meaning there is no pore size larger than 0.1 micron in size. This makes it impossible for harmful bacteria (like salmonella), protozoa, or cysts like E. coli, Giardia, Vibrio cholerae, and Salmonella typhi to pass through the filter.
All Sawyer water filters meet or exceed Environmental Protection Agency (EPA) recommended removal rates.
