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.

Specifications

From the Sawyer PointOne Amazon page.

  • Complete water filtration system designed for emergency preparedness, groups in the backcountry, and mission trips
  • Removes greater than 99.99999% of bacteria
  • Removes 99.9999% of all protozoa
  • Bucket and faucet adapters provide high-volume clean, potable water from any fresh water source; easily field maintainable
  • Filter with built-in and removable push/pull cap; comes with one 32-ounce, BPA-free collapsible pouch for personal hydration
  • Backed by manufacturer's lifetime limited warranty (Independent Testing Laboratory Hydreion, LLC.; Microbiological Report S05-03)

Now for the video showing the setup.


I was very impressed with how fast the Sawyer PointONE filtered the water. The flow was almost instant, which surprised me.

This would be an excellent set up for a camping trip. Staying at one location for several days? Get a two or three liter water bladder, and the Sawyer PointONE can be used to filter water for everyone in the camp.

Even on a hiking or backpacking trip this would be a nice setup. No more getting the old style pump water filter out and pumping water. Just fill the platypus bag, and hang it from a tree limb or from the side of a tree.

I have been using pump filters since the 1990s and am getting tired of them. The goal is to find something that allows me to spend more time enjoying nature, and less time filtering water.

It may take a few minutes to set the Sawyer PointOne gravity water filter system up, but it beats kneeing down in the dirt to use a pump filter.

Kevin ~ I've been using the PUR pump for backpacking since the early 90's and have gone through a few of them up until this point.

This gravity setup is the exact reverse of what I have been historically doing when a camp sight has been established for the day. Usually I am using the pump to fill up a sun-shower bag, or some other bladder to store a good water supply for the duration of the stay at the temporary camp. Pumping on the fly to fill canteens, while on the move, is where the pump-filters mobility is useful. Very little hassle to fill those smaller receptacles in only just a few minutes.

When attempting to fill large receptacles, like the sun-shower bag, spending long minutes hunching over a creek bank gets tiring. That seems to be where this gravity feed approach is more desirable. Just quickly scoop up large quantities of water and let gravity do the work, while you are setting up tents, or cutting firewood. When I saw gravity filter I presumed "Drip Filter", but that flow rate rivals pump filters.

I looked at the Amazon page for the Sawyer and see that it is a Squeeze driven system. Great job at retrofitting it for gravity feed. Smartly innovative.

Thank you.

Yes, wading into a creek to fill a bag, or finding somewhere near the bank where the bag can be can be aggregating.

So far the pump filters seem to be the best all around filter. I have filtered water from a stream barely an inch deep, all the way to river water.

A gravity filter would be difficult to use with a shallow water source.
