Bacteria Battling Water Bottle Uses UV-Blasting Cap

Camelbak's best known for its water-filled backpacks, but instead of focusing on just hydration, the company's new All Clear bottle incorporates a bacteria-eliminating ultraviolet cap for those times when you have to fill up from a non-filtered source.

Instead of replaceable filters or chemical additives, to purify 740mL of water, all you have to do is fill the bottle, securely attach the cap, turn on the ultraviolet lamp and then shake it for 60 seconds. The process is claimed to kill 99.9999 per cent of bacteria, 99.99 per cent of viruses, and 99.9 per cent of protozoic organisms.

Just keep in mind the $US100 bottle is being positioned for recreational use instead of hardcore survival. You should be fine when filling it up from a lake or a stream, but dirtier and stagnant sources of water will probably require a more complicated purification process to remove sediments and other harmful things that could make you wish you had just stayed thirsty.
