The Sawyer Cleaning Coupling offers an alternative way to clean your Sawyer Squeeze filter or dual threaded MINI filter using a standard plastic bottle.
To clean your filter with the Cleaning Coupling, remove the push-pull cap from your filter, attach the Coupling, then screw the other side of the Coupling onto a bottle filled with clean, filtered water. Once attached, you can forcefully squeeze the bottle to backwash and clean your filter.
Great tool in making a gravity filtering kit with Vectos, water bottles or other collapsible containers.
NOTE: This coupling only works with 28mm threads. This will not work with a BeFree filter or our 42mm Vecto.
