Even if you’re filtering floodwater with sewage in it, you can make the water crystal clear and safe to drink with this rechargeable, featherweight purifier ($119, rei.com). It’s the only one on the market that kills all levels of microbiological contamination with a simple mechanical pump, and you can use it up to 8,000 times. It's also rechargeable via USB if you have a USB solar charger. (In November 2012, the SteriPen Freedom will come with its own solar charger, as well.)
