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 PointOne filter does but now in a more compact, personal size. 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%) of all bacteria (like salmonella) as well as other harmful bacteria which causes cholera and E. coli and 6 log (99.9999%) 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 PointOne filters allow. Attach the Mini to the included drinking pouch, use the included straw to drink directly from your water source, connect it to hydration pack tubing (sold separately), or screw it onto standard disposable bottles (28 mm thread).
