Cleaning Coupling

The Sawyer Cleaning Coupling offers an alternative way to clean your Sawyer Squeeze Filter or dual-threaded MINI filter using a standard plastic bottle. Simply remove the push-pull cap from your filter, attach the coupling, then screw the other side of the coupling onto a standard plastic water or soda bottle (28mm thread) filled with clean, filtered water. Once attached, you can forcefully squeeze the bottle to backwash and clean your filter. Repeat as necessary until the water comes through clear and easy.
