0.1 Micron Absolute Filtration
Our water filters contain a high number of tiny ‘U’ shaped hollow fiber micro-tubes that trap contaminants while allowing decontaminated water to freely pass through at a high flow rate — eliminating the need to store water and reducing the possibility of water contamination after the filtration process.
The Sawyer Point ONE (the filtering mechanism for the 3-Way Inline Filter) is certified for 0.1 micron filtration, meaning there is no pore size larger than 0.1 micron in size. This makes it impossible for harmful bacteria (like salmonella), protozoa, or cysts like E. coli, Giardia, Vibrio cholerae, and Salmonella typhi to pass through the filter.
All Sawyer water filters meet or exceed Environmental Protection Agency (EPA) recommended removal rates.
Use the lightweight 3-Way Inline Filter water treatment system to filter water directly from a river, lake or stream along the trail, or from other non-potable sources. It also works great as a hydration pack reservoir filter for long hikes where the water source is in question. You can even just attach it to a household faucet filter with the included adapter.
For hydration packs, insert the filter inline with the drinking tube, then simply fill your reservoir with unfiltered water and drink away. As long as the filter is inline with your hydration pack’s tubing you don’t need to worry about cleaning the reservoir. You can also attach a drink tube or straw of your choice (sold separately) to the filter, then submerge the filter into dirty water and drink directly from the source.
A Lifetime Of Clean Water
The Point ONE’s filtering membranes are sturdy enough to withstand backwashing, restoring up to 98.5% of the filter’s flow rate. This allows the Point ONE to be cleaned and reused almost indefinitely with no expensive cartridges to replace… ever. We recommend backwashing and sanitizing the filter after every outing for optimized use.
