The Sawyer Products proprietary hollow fiber membrane filters are small, portable, easy-to-use, reliable, inexpensive, and can last a decade without needing to be replaced.
These filters are certified for ABSOLUTE microns making it impossible for harmful bacteria, protozoa, or cysts like E. coli, Giradia, Vibrio cholerae and Salmonella typhi (which cause Cholera and Typhoid) to pass through.
Just drink: no pumping, no chemicals, no waiting, no Worries! Incredibly fast flow rate, simple to use, and each filter can be backwashed to extend its life. We're so confident in our filter technology, most Sawyer Water Filters come with a 1 million gallon guarantee.
Standard survival procedure says to assume that all water you find in the wild is contaminated. New hiking gear like pocket purifying pens make cleansing drinking water easy, but it's wise to know how to filter and boil your drinking water without such a device, just in case you lose it or forget to bring it with you. Remember, redundancy is your friend!
