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 connect the dirty 1-gallon reservoir to the second clean water 1-gallon reservoir with the included tubing and MINI filter, then fill the dirty bladder with water from any source. Gravity does all the work of filtering clean water into the second bladder.

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.
