1 Million Gallons Guaranteed
We didn't actually run a million gallons through the filter, because that's a lot of water... but we could have! We are confident in our million gallon claim because you can continually clean the filter by backwashing it with clean water. So there really is no end to its useful life. Follow the helpful hints included in the directions for use. Backwashing is not required often unless you are filtering very turbid water. Backwashing only takes a few seconds. If you are accustomed to a ceramic filter, the leaning ratio is approximately 20:1. In other words, by the time you first need to clean your hollow-fiber filter you would have neeeded to clean a ceramic filter 20 times. NO REPLACEMENT FILTERS OR CARTRIDGES ARE NECESSARY.

The Sawyer® Water Filters feature a 0.1 Micron Absolute Hollow Fiber Membrane, which uses medical technology developed from kidney dialysis. When the water is drawn through the filter, it flows through the side walls of the Hollow Fiber tubes. Sediment, bacteria, protozoa, cysts, and other contaminants are filtered out exceeding all applicable EPA recommendations.


Extremely Cost Efficient
One Sawyer Bucket Purifier system can provide clean water for a small village for pennies a day. These filters and purifiers make water so clean and accessible that people will not only use the filtered/purified water for drinking, but also for cleaning, bathing, cooking, watering plants and more.

Fast Flow
This is a POINT OF USE SYSTEM. Since there is such a high flow rate, this eliminates the need to store water which reduces the chances of water being contaminated after it is filtered. The only external force required for the system to function is GRAVITY.
