Potable fill-up

CamelBak pioneered hands-free hydration via backpacks with integrated water carriers linked to long plastic straws. Now the company has created a more conventional-style water bottle with a water purification system built into the lid.

The All Clear Microbiological UV Water Purifier system uses high-powered ultraviolet light that, when activated, neutralizes more than 99 percent of waterborne bacteria, viruses, and protozoa, sterilizing the bottle’s 750 milliliters (about 25 ounces) in 60 seconds. The lamp is powered by a built-in rechargeable lithium ion battery; one five-hour charge using the included mini-USB cable — which plugs into the cap — is good for about 80 purification cycles.

Just fill the water bottle, secure the screw-on cap, hold the power button on the cap down for two seconds until blue light illuminates the water, and then rotate the bottle allowing the ultraviolet light to destroy and neutralize waterborne viruses and bacteria. Then unscrew the cap and chug. An LCD screen on the cap displays the countdown from 60 seconds to drinkable, and also has a battery gauge so you know when a recharge is due. The bulb is guaranteed for 10,000 cycles, which is enough to purify about three liters per day for seven years.
