Good portable water purifier for backpacking

[Great-Kazoo]

I posted this in another thread, but this filter I picked up is built to last. I wish it would filter down lower on the micron scale, but I think pairing it with uv could be the way to go.

If you're using a portable filter, access to UV (outside of sodis) and on the go will be minimal.

I have a First Need that I trust. http://www.rei.com/b/first-need?s_kw...t|bp|bing|main

I don't generally begrudge the weight in my pack. If you don't mind waiting while the chemicals do their thing, or dealing with a certain amount of ... stuff ... in your water, purification tablets or chlorine dioxide drops (http://www.rei.com/product/866996/aq...reatment-drops) are cheap and light.

I was in Yosemite high country for a while this summer and used both the First Need purifier and the Aquamira drops during different periods.

+1 for the sweet water as well.

What's the consensus on those water bottle filters like the CamelBak Groove and Brita's offerings?

J. Let me put this in a matter of numbers when you look these suggestions up.

Domestic threats are usually .5 micron or larger. 3rd world threats are as small as .05 micron. Chemicals can bridge the gap on filtering but if you're starting from scratch getting something that will for sure do the job then overkill with chemicals and have a great trip.

I'm looking at something like this to use after filtering.

Katadyn makes good quality stuff in a small package.
