UV light is a common method for purifying water, but there aren’t too many portable options. One is the SteriPen, a device you dip into a glass of water. But Camelbak has a new option, the All Clear bottle. All Clear is a 0.75 liter water bottle with a UV light built into the cap. Once filled, the light operates for 60-seconds to sterilize the water.
The All Clear bottle has an internal battery that can be charged from a wall socket, USB or the power source in a car. One charge should operate for several days in the wilderness. Camelbak says the bottle is effective for use with untreated water such as filling from a stream or a spigot that you’re unsure of. It’s also effective in treating water when traveling in other countries.
Camelbak has several videos showing how the bottle works, and how it was tested to make sure the light is as effective at the end of its life as at the beginning. One drawback of the $99 bottle is that it doesn’t appear to have the typical Camelbak bite valve and straw, or other means to drink from the bottle – other than sipping from the open bottle. It does appear that the bottle is the same size and form as Camelbak’s other 0.75 liter bottles, and therefore it should be fairly easy to swap caps once water is sterilized. Another add-on to the bottle is a filter, Camelbak makes a filter that covers the top of the bottle when you’re collecting from a stream or fresh water source where you might otherwise pick up sediment and other debris.
