Turn your Purist water bottle into a filtration system with the Extract Water Filter, which allows you to refill your bottle from any fresh water source. The Extract filter is unique in that you’ll no longer need to bring a separate water filter on a ride, and it’s designed to screw onto any Purist water bottle. Simply fill your bottle in a stream or spring, screw on the cap, and drink from the bottle as normal.
