The Sawyer Mini is ideal for outdoor recreation, hiking, camping, scouting, domestic and international travel, and emergency preparedness. This high performance Mini filter fits in the palm of your hand, weighs 2 ounces, and filters up to 100,000 gallons (30 times more than comparable filters). It attaches to the included drinking pouch, standard disposable water bottles; hydration packs, or use the straw to drink directly from your water source. 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 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.
