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.
