Good portable water purifier for backpacking

[hollohas]

I have been using the MSR Sweetwater for at least a decade. Very easy pumping action (pumps on up and down stroke), very fast filtration rate, cleanable and replaceable filter, included pre-filter screen. Handle folds slightly to make it pack a little better. It's not as small as the sawyer, but I have hundreds and hundreds of miles with it in my pack and it NEVER got in my way. Makes the best tasting water I have ever had. If you want to have the best protection from the smallest viruses (probably a good idea in foreign lands) also get the drops.
