I have been using this purifier for a few years now and ran into trouble on a trip where temps where hovering in the low teens. I had a hard time making the brine solution required for the chemical reaction with the cold water. I also had a problem with my original battery in the low temps. My friend was carrying the UV light treatment device and it worked fine but he needs 4AA batteries which makes his much heavier. This is great for mild weather, tastes fine, and is super light. I still trust it more than anything else on the market if you can get over any particles from the lack of filtering.
