Questions: Water Filter Systems????

[Mike]

As a back up I bought a second filter for the gravity works system.  It is basically a life straw.  I also had one of the MSR hand pump water filters.  You will earn every oz of water you pump thats for sure.  Plus they take a very long time to pump any real amount of water.  As IdahoNancy stated the gravity works is a set and forget system for the most part.  Good luck
