SteriPEN harnesses the power of ultraviolet light to make water safe to drink. It’s the same technology used by leading bottled water manufacturers, as well as major cities in the U.S., Europe and Asia to purify water.
SteriPEN’s UV light technology eliminates over 99.9% of bacteria, viruses and protozoa that cause water-borne illness. SteriPEN purifies 16oz. (0.5L) in just 48 seconds; 32oz. (1.0L) in just 90 seconds. All without any pumping, timekeeping, or any added aftertaste or chemical odor.
Add solar charging to the Adventurer Opti for complete freedom on or off the grid. Solar charging clamshell case pulls double duty: recharging the rechargeable CR 123 Lithium Batteries and providing handy, secure storage for the purifier. The SteriPEN Adventurer Opti uses an optical eye to sense the water. This technology ensures safe use and provides purification in even the coldest of waters.
The new optical sensor doubles as a convenient LED flashlight. It’s a great backup light when camping or taking a night-time walk to refill your water bottle. The Flashlight mode is activated by pressing and holding the single button down for 3 seconds. The clear lamp cover focuses the LED light.
