Best water filter by far!

I own 3 of these. They work awesome, and last a long time. Make sure to back-flush the system frequently (I do it about every other bag of dirty water) and it will treat you right for many years. Brilliant design and extremely functional.

I have not used it

Compact size & may come in handy to filter water for human consumption.

Makes camp chores efficient, at first

Platypus GravityWorks 4L Water Filter System is great for filtering water, why you cut wood, adjust your gear or shelter.
But after a few uses (in a fresh spring) the filter time nearly doubled.
I tried clearing the tubes and filter by blowing them out, but it did not help.
On my recent 2-week backcountry trip, I could filter 10 liters of water through my Katadyn Vario Water Filter faster than the Platypus GravityWorks filtered 4L.

Works Great!

I recently got back from a 9 day elk hunt and we used this filter system on a regular basis. It's very simple and efficient. We were blown away by how fast it can filter water!
