SteriPEN Adventurer is the ultimate tool to take on outdoor adventures for safe drinking water anywhere on earth. With the SteriPEN Adventurer, you're carrying hundreds of gallons of pure water in your backpack while adding only 110 g (4oz.) to your pack weight.
The Adventurer uses ultraviolet light (UV) to destroy the DNA of microorganisms making them unable to reproduce and cause illness.

It's effective against outdoor microbes like giardia and cryptosporidium; pathogens that cause diarrhea, dysentery, hepatitis, and Legionnaire's Disease; household germs such as bird flu, E. coli, and salmonella; staph and strep; and natural-disaster risks like botulism, cholera, smallpox, and typhoid.
No pumping, no chemicals, no test strips, no timekeeping, no lubricating, and no replacement filters are required. All that is required is to push the water purifier's button (once for 16 ounces, twice for 32 ounces), place the pen-like lamp in clear water, and stir until an indicator light turns green.
