The Sawyer PointONE is my new favorite water filter. Depending on water conditions, it can filter up to one millions gallons, and the flow rate beats the Sawyer Mini water filter hands down.
However wonderful the Sawyer PointONE water filter is, the user still has to either fill up a bag or water bottle, then attach the bag or bottle to the filter. Filling a water bottle with a small opening can be a pain, and sometimes an act in frustration. Rather than using the bag that was included with the Sawyer PointONE water filter, I bought a two liter platypus bag. One end of the platypus bag opens, and water is simply scooped up from the water source.
Think of the platypus bag as large heavy duty ziplock bag with a hose attachment. The bag can then be hung from a tree limb, or from the side of a tree. From there a plastic hose is attached, with the Sawyer PointONE water filter inline between the platypus bag and the water bottle.
