Home Forums Hunting & Shooting Backpack Hunting What water filters are you using?

I'm in need of a water purifier to keep in my kayak. We're going on some four and five day trips this summer, some river and some in Voyageurs National Park/ BWCA.
I need one that will easily purify enough water for two people. It will be used in northern Minnesota mainly where the rivers are clear and the lakes make you want to drink right out of so filter clogging shouldn't be a problem. Size and weight can be more that you may want to carry in a backpack but it still matters. Thanks
