Lifesaver water bottle | Emergency Preparedness | Forums

anyone have experience with these?

Traveling to developing nations and disaster zones just got a lot easier. The remarkable Life Saver bottle has an affordable, portable carbon filter that can block any virus larger than 15 nanometers. What's more, it can go through more than 1,500 gallons of water before the filter needs to be replaced. The bacteria and virus retention rate is 99.99 percent effective -- it's so thorough that it's even supposed to clean up (gulp) fecal matter.

The bottle was inspired by the aftermath of Hurricane Katrina when visiting businessman Michael Pritchard found that thousands of survivors couldn't access clean water. The only drawback seems to be that it doesn't work in freezing temperatures.
