A SteriPEN Adventurer! As I finally begin to enter into the world of water safety. I don't preclude having a filtering device, for the times I'm dealing with turbid water. Usually, the water I deal with at least "looks" clear and safe, and the SteriPen will disrupt the DNA in protozoans, bacteria, and viruses. I can't wait for spring so I'm testing it now, in Nalgene jars.

Actually, the product is good for travelers, or during any time when safe drinking water cannot be counted on.
