Use the Sawyer 1-Gallon Gravity Water Filtration System to filter large quantities of water as quickly as 7 minutes. The dual-threaded MINI filter makes an ideal addition to your backpacking, backcountry camping, emergency supplies. Certified for .1-micron filtration, this system removes 99.99999% of bacteria (salmonella, cholera and E. coli), 99.9999% of protozoa (cryptosporidium and giardia), and 100% of microplastics, exceeding EPA recommendations for removal rates.
