A pair of international trips this year have netted me multiple bouts of stomach sickness. But you can’t say I haven’t tried to allude the little bugs that cause ill will to so many travelers.

One weapon I’ve employed, the AdventurerOpti device from SteriPEN is marketed to kill viruses, bacteria and protozoa such as giardia and cryptosporidium with ultra-violet light. The handheld product is a miniaturized version of UV-light technologies used in municipal water-purification plants around the world.

SteriPEN AdventurerOpti Review

Traveling in Nepal last month, the AdventurerOpti was constantly at my side. The product is small, easy to use and quick: Press the button, dip the lamp into your drink, and wait 90 seconds to purify a liter of liquid.

The AdventurerOpti is a new version of the SteriPEN product, which has been on the market for a few years. It is slightly smaller and lighter than other SteriPEN models.

My stomach issues while traveling may have been from sources foodborne, waterborne or even airborne — it’s impossible to know. I used the SteriPEN 90 percent of the time when drinking water procured outdoors from lakes and streams as well as in restaurants where tap water was served.

The $89 product worked as promised as far as I know. But it is one of those items that you simply have to trust does what it says it will do. Water looks or tastes no different after UV purification.

For really dirty water, the SteriPEN will not work. Water has to be mostly clear for the product’s UV light to do its trick. Murky water from lakes or rivers has to be filtered before the SteriPEN can be used.

On my travels, I will continue to tote a SteriPEN along. I will use it in the outdoors for backpacking and climbing trips as well as when traveling internationally. In the end, the AdventurerOpti is an insurance policy, an extra step in the fight against the little bugs that can make the stomach sick.
