Most backpacking water filters only take out bacteria and protozoa, but the Grayl filter takes it a step further by also removing viruses. This is especially important if you are traveling to a part of the world where norovirus is a real concern. The titanium models are a little pricier, but give the filter a sleek appearance. You can also use them as a cooking pot in a pinch.
