Sawyer mini gravity bottle adapter

Screw the adapter to your water bottle/bag and put the outlet of the sawyer mini filter through the v shaped opening on the side and let the water bottle hang from the filter. The larger the volume of water to be filtered the faster it will go. 20 oz. of dirty water took about 30 min. to fill a 20 oz. bottle compared to 72 oz. of dirty water took about 5 min. to fill the same 20 oz. bottle.
