The Sawyer Mini water Filter is a second generation Filter that is the lightest and most versatile personal filtration system from Sawyer. With a total field weight of 2 ounces it fits in the palm of your hand. This tiny Filter does the same job that the Sawyer point one Filter does but now in a more compact, personal size. Filtering up to 100,000 gallons of water, this may be the last water Filter that you BUY. The Sawyer Mini Filter is perfect for everything from camping with the kids to traveling abroad where tap and bottle water cannot be trusted. The Filter removes 7 log (99.99999 percent ) of all Bacteria (like salmonella) as well as other harmful Bacteria which causes cholera, and e. Coli, and 6 log (99.9999 percent ) of all protozoa such as giardia and cryptosporidium. These removal rates equal or exceed other Filter options. Epa guidelines allow ten times more protozoa left in the water than Sawyer point one filters allow.
