Platypus GravityWorks 4L Water Filter System

Jason Fisher
Worth it!!

I went on a backpacking trip into the high Uintahs with 15 people. This cranked through mountain lake water like I have never seen a filter do before. It is light weight and no pumping! We literally filtered 50 liters over 3 days and again no issues. You do have to back flush and clean but way easy. Worth the money!

Highly recommended

Filtration system answers any issue I had with my msr pump, leaves more time for glassing, fishing, setting up camp, etc. It’s just better and lighter as long as a good water source is found. Friends are already getting their own after seeing mine


Favorite backpacking water filter!
