Playpus CleanStream

This gravity-fed filter uses the same micro-tube-based filtering technology as the MSR Hyperflow. The review of the Hyperflow says everything you need to know about the CleanStream. Mine completely clogged within three liters of dirty water; water that I had no choice but to use. A filter that must be babied as to the quality of water it processes is useless. I was suspicious of the thing but lured by the lower weight and lack of pumping.

I'm very happy that I had enough chlorine tabs for the short trip that I was on.
