From Sawyer, Inc.:
With the technology derived from kidney dialysis, we partnered with a fiber manufacturer to actually improve the hollow fiber membrane technology. In order to improve both the filtration rates and longevity of the filter, our team was dedicated to engineering something even more precise and rugged. To make it a superior solution, the fiber composition had to deliver exactly 0.1 & 0.02 micron filtration 100% of the time to ensure no bacteria would get through. Moreover, the membranes had to be sturdy enough to withstand back-washing which allows the filter to be cleaned and reused.
Our proprietary water filters are comprised of tiny “U” shaped micro-tubes that allow water to enter into their core through minuscule micro-pores. Contaminates get trapped in the tubes while the decontaminated water passes freely through. The high number of those tiny tubes and their significant surface area allow the filter to have one of the fastest flow rates available in the world. This high flow rate makes our filters easily utilized as point-of-use solutions, which has eliminated the need to store water – one of the leading causes of contaminated water throughout the world. Each Sawyer filter is certified for ABSOLUTE microns; that means there is no pore size larger than 0.1 or 0.02 micron in size. This makes it impossible for harmful bacteria, protozoa, or cysts like E. coli, Giardia, Vibrio cholerae and Salmonella typhi (which cause Cholera and Typhoid) to pass through the Sawyer PointONE™ biological filter. At 7 log (99.99999%) the filter attains the highest level of filtration available today.
Sawyer’s revolutionary technology has also been tested and verified by the United Nations, and is currently being used in more than 70 countries around the world. Sawyer’s filters are so powerful, they could not actually be used for kidney dialysis anymore, as they would now remove beneficial particulates from human blood. They’ve been field tested for years by dozens of companies and professionals and are solving the global water crisis for hundreds of thousands of individuals internationally.
When it comes to ensuring the safety of those who have trusted us to provide the most advanced solutions on the market, nothing less than 100% is good enough. All Sawyer Hollow Fiber Membrane filters are small, portable, easy-to-use, reliable, inexpensive, and can last a lifetime without needing to be replaced.
