No matter how far you go "off the grid," you'll always have clean water for drinking, dishes, washing up and more. This Filtration System provides up to 1 gallon of potable water in as little as 7 minutes. And at a lightweight 4.5 ounces, it's easy to carry in your pack. Simply fill the included gallon-sized water bladder with unfiltered water, attach the MINI filter and hose (both included), then let gravity do the work of filtering clean water into your bottle. The dual-threaded MINI is certified for 0.1-micron filtration. That means it's impossible for harmful bacteria (like salmonella), protozoa, or cysts like E. coli, Giardia, Vibrio cholerae, and Salmonella typhi to pass through the filter. And that makes it the ultimate lightweight solution to get clean water while you're hiking, backpacking, camping, hunting—and enjoying the Great Outdoors.


  • Gravity-powered system. Dirty water trickles from the water bladder through the MINI Water Filter until it's clean
  • Filter removes particles, protozoa, and bacteria down to 0.1 micron in size, including giardia, salmonella and cryptosporidia
  • 0.1-micron Absolute Hollow Fiber Membrane uses pore sizes so small for the highest level of filtration available
  • Filter has threads on both sides for easy on/off functionality while filtering
  • Dual threads are also compatible with the cleaning coupling accessory for backwashing the MINI into a 28mm threaded water bottle

  • 1-gallon Mylar® Gravity Bladder
