We have covered several water filter systems here in the Loadout Room. Everything from the smaller portable filters to the larger family size filter systems. I typically have some type of emergency filter in my pack when out on the trail or in the woods. They are a nice option to have if you run out of water and don’t have the time to start a fire to boil water.  Dave Canterbury of Self Reliance Outfitters covers a few different options and gives his professional opinion on each.
